I'm quite sure the extensions system only will be successfully if all missing core features have been added to the core.
I do not understand what you mean by "missing core features".

As far as I know AutoMOD should continue to work for installing MODs on 3.1. I have not tested it, but I do not see why it wouldn't. But because we are trying to phase out MODs, it would be counter-productive to include it. It will continue to be available for download, as far as I know, when phpBB 3.1 is released.

Extension Manager installs Extensions, not MODs. They are completely different.
