I think that this is wrong and I will give you a use case. Imagine, for example, that I have a package which I add to ELPA when Emacs-26 comes out. I maintain this package and expand it slowly. Then, when Emacs-27 comes out, for example something significant has happened (say, just for argument sake, the advice system got re-written -- unlikely, but it could happen). As a package author, I have two choices here: either I move to Emacs-27 and ditch Emacs-26 support. Or I have to put runtime conditional logic which supports both. I think package authors should have the choice of freezing the Emacs-26 version of their package when Emacs-27 comes out. This situation would get worse if we have an "unstable" version of ELPA. I bet that there is some package already that depends on Emacs-27 at the bleeding edge. Phil
