So Now with the extended 2020 1040's deadline of May 17, 2021, IRS however has not extended

the 2021 1st Est 1040 payment of Apr 15th, 2021........why wouldn't they make them the same, since 2020 1040's info probably will be delayed due to the T/P knowing they have more time or some other factors?

Seems to me in my limited expertise, wouldn't it be better if they just do as they did last year, and move everything to the July 15th and be done with making further changes, given all these issues we as accountants are dealing with during these challenging times......PPP's. EIDL's, ERTC, EIP's, possibly more filing of 1040-X's, and of course the Pandemic, and so on?

Granted, I'm sure some of us would rather just get it over with by May 17th and go relax for a few days or weeks on some exotic Island!
