So I don't think you can use the new 'interactive' syntax there.So packages on ELPA are allowed to be ahead of those in core, but not vice versa? Is that really the intent that we allow them to diverge, but only in one direction?What do you mean by "ahead"? Have a newer version of the package in 'master' and some other in ELPA?Not necessarily "newer", but one that relies on features that exist in the Emacs version with which it is bundled.
This can be done with either maintaining a separate version of python.el somewhere in a different repo, or with version checks inside the main file, compatibility aliases, etc.
Neither seems warranted for the feature in question, since we have a backward-compatible syntax as well.
Then we (someone? who?) either have to maintain both version, or accept that ELPA and all users of Emacs 24-27 won't get any subsequent updates to python.el, including support for newer Python syntax, etc.I don't think I understand why. We are talking about changing python.el on master, which will be released with Emacs 28, in some not-too-close future. What does that have to do with users of older Emacsen receiving updates to python.el? I guess I'm confused here.
Emacs 27 users can install the most recent version of python.el from GNU ELPA. This is generally a good thing.
Either approach can work in ELPA, but our "ELPA core" scheme aims to make new features available to as many users as feasible, while limiting the extra support effort required.The new features on master will be available only when Emacs 28 is released, until then they cannot possibly do any harm to anyone. Right?
I meant the "new features" of python.el (not of Emacs 28 core) and of other "ELPA core" packages.
