This will break the compatibility layer for all old MediaWiki installations and
any extensions relying upon them.

You think? Actually, do we need extensions for old MW versions? People, who need them, just have to switch to older SVN revision

Trying to dig through the revisions is too much of a pain.

We did start branching extensions. But I don't know how well the backporting et all will be, so I'd take that with a grain of salt. Also, some extensions are not on SVN.

I do not see any benefit in breaking a perfectly good compatibility layer, nor do I condone gratuitous breakage of backwards compatibility.

I strongly recommend against using ExtensionFunctions.php as it's a pain in the ass. Extensions should be self-sufficient.

I'd have to agree, I've seen floods of "this doesn't work" threads and IRC complaints because of this.

Yeah, I mentioned that in #3. We should leave extension functions alone. Rather, just replace all uses of it on SVN.
