Perhaps. So let me clarify a little.

What I originally though you meant, it adding a filter by major modes 
for non-file-visiting buffers. That kind of makes sense, but that kind 
of filter shouldn't depend on the project in question (it could, but 
that, again, would make things more complicated; so let's work with the 
current model first).

On the flip side, *some* projects could specify that they only work with 
certain major modes. But a lot of projects won't specify that. And we 
need these commands to work in both cases. So discussing the projects of 
the former kind is, again, a complication, and I'd rather we did that 
later in a separate discussion.
