Unless your changes apply to Emacs I don't think they are really
redundant. I think the key thing is agree how it ought to work, so we
end up with the same model, but I don't anticipate any problems there.

If you still have these, I would appreciate a copy, so that I don't have
to reinvent them. Are they in your git repository?

There may be some on the CEDET site. I don't remember seeing any on the
wiki or elsewhere.

Well... nominally. It is still a buggy mess.

I will have to think about this. This would imply removing all those
slots from struct buffer; I suppose my concern would be that the result
would be too inefficient.
I've also been considering a similar thing for the Vfoo globals: remove
them and have the C code always refer to them via SYMBOL_VALUE.
