Can you use registers today to jump to buffers that are connected to
files?  I'm wondering why you're singling out non-file buffers here...

But in general, it seems to me that these keystrokes aren't that much
more efficient than just C-x b scr RET or something.

Hm...  I don't quite see the utility here.
