I knew it was getting added, but wasn't sure how compatible it would be with older versions. Not 100% sure about best migration strategy. On one level, providing the ability for users to choose which interface sounds nice, but on the other, a main goal is to simplify code and reduce maintenance. Providing a choice will actually complicate matters and increase maintenance. Is the transient.el included in Emacs 28 the same as the one on GNU ELPA? I'm assuming it is, but I have to admit I'm still not 100% clear on how Emacs handles the situation where you use a library that is both built-in and available in ELPA. Does Emacs use the latest version available or does it use the built-in version until you explicitly select the ELPA versions?
