Hi,

I’ve recently come across an interesting looking library available on ELPA, https://git.sr.ht/~pkal/compat. I’m thinking in future this could allow us to both use newer features and also support older versions of Emacs, e.g.

Org 10.X is developed for Emacs 28.1 and newer, but supports Emacs 24.3 and newer with compat.el.

Just tossing this out as an idea :)
