Where would they integrate it. Emacs is a small core of C code. Almost everything is Elisp and in the same standing as third party packages. I’m not seeing what being in emacs core brings to an AI package?
That would be a reasonable stance if the difference were in incubating a new project vs excluding functionality from blessing because it interfaces with non free software. The functionality I'm talking about is excluded because of the latter.
Well the linking into GCC was a C code issue. For emacs, there is a large collection of elisp that is shipped with the official package. Preventing worthy enhancements of that core package solely in the name of a distorted view of freedom hinders emacs and the adoption of emacs.
