EDE is Emacs Development Environment, is shipped with stock Emacs and is recommended to be turned on as a global minor mode, in the official Emacs Manual, Section 25.4, page 330 of the printed version, or 352 of the pdf.
It's not a 'mere keybinding conflict', it's a conflict that anyone reading the official manual would be bumping into. It's not some obscure tiny extension no-one is using, it is an official part of Emacs, just as Org is.

I don't know what is EDE. Anyway I don't think a mere key-binding
conflict deserves an entry in the "Conflicts" section.
It's true that Org shouldn't have used `C-c .` and `C-c !` in the first
place, but that ship sailed long ago.
