I respectfully disagree with you and [MENTION=142432]Titan24[/MENTION] on this.
Sometimes a mistake is made in selecting someone ahead of more deserving alternatives.
Neither Imran Butt nor Saud Shakeel opened in QEA this season, and the selectors chose the wrong player.
And to persist with that is to compound and exacerbate the original mistake.
Imran Butt will never be good enough, unfortunately.
		
		
	 
I agree that a mistake can be made in selection but its not just Imran Butt and there are countless such examples. The problem i think is that there is no accountability and no questions are asked people making mistakes if we look through the history and when a player is dropped after one or two matches it sets a wrong precedent. It naturally creates insecurity among the upcoming players that if they got selected will they ever get a match and if they do will it be one match or two matches. I dont think its the right environment to create for development of any player.
Lets discuss just a few examples out of the pool from last few years:
Usman Salahuddin: Got selected for Eng 2018 tour with a really good FC record. Played one match in the absence of Babar, looked better than some of our veterans and got dropped.
Mohammad Asghar: Got selected as backup of Yasir Shah in 2016 at 18 years of age in Aus and after that Asghar never to debut and in 2018 Bilal Asif came out of nowhere to debut.  
Mohmmad Rizwan, Sadaf Hussain and Usman Salahudin’s selection in ODIs in 2012: So these three guys got selected for the WI ODI tour in 2012 and while Usman was given couple of matches after which he was dropped the other two never even get to play a match before being sidelined forever in the case of Sadaf and quite a few years in case of Rizwan.
Zafar Gohar: In 2016 he was almost set to debut before he missed his flight and then somehow he wasnt good enough to be even looked at for 4 years. Again selected for NZ tests in 2020, plays one test and is now dropped.
Players struggling due to transition of selection committee:
Imam ul Haq and Sohail Khan: Were travelling with the team for almost last two years and now without playing a test since a long time, they have been dropped.
These are just few examples from quite a big list.
I might not be huge fan of many of these selections to start with but, my point is how so many mistakes can be made and it carries on without any accountability? Are the selectors not watching the matches live and they are just going by stats? 
I think it can possibly sometimes be more to do with the backlash after some poor performances that they make scapegoat out of some players or they just couldnt handle the pressure of backing someone who they think can turn out to be good than it has to do with it being acceptance of the mistake. I cant imagine the possibility of watching someone closely for whole season (I am assuming they do) and then dropping them after never giving them a match or one or two matches. If Pak would have lost the series than Imran Butt would have been an obvious name to go which would have proved my point but, history is there to be seen which will manifest similar examples.
I think its not the right environment to have for young players who might be watching so much of lack of judgment and lack of clarity from the outside. 
I am not fan of Imran Butt the current batsman but, he is just going to be another addition to the list of selection mistakes by being dropped after two tests hampering the overall morale of the players in circuit and the environment.
Misbah selected him and Moh Wasim retained him for this series citing his catching as one of the reasons. It is pretty poor if they both are judging someone incorrectly. There is no harm in correcting a mistake but, how many mistakes will be made before being rolled back? 
It does happen in other countries as well sometimes but, the scale is much lower based upon what I have observed. This rolling back and correction of mistakes comes at a cost of the overall morale of the team and domestic players so I think that should be kept in mind before making such mistakes.
P.S: So for me its not about Imran Butt rather the culture as a whole which needs to improve.
