That's true, but they do happen. Emacs is not fully 100% backward
compatible.
I don't have the biggest of pictures in my head, but for me the solution
lies in providing more and more packages as :core. In the Eglot circle,
for example, most of the flymake.el, project.el, xref.el, jsonrpc.el
dependencies are themselves :core ELPA packages. So Emacs 26.3
users can use Eglot with all the latest and greatest that is in trunk,
Just my 2 cents,
João
