My point is that we could make them all, normally, not self-inserting.

I see. I hadn't considered that scenario...

...though, come to think of it, I routinely use a Compilation-based mode 
(rspec-compilation-mode), where I need to switch to a different major 
mode temporarily for debugging and shell-like interaction, and then back 
to rspec-compilation-mode when I'm finished. That works okay.

So it wouldn't be too terrible if the major mode is switched to 
something else when the process finishes. The user will likely learn 
than quickly, and managing to type 'g' before learning it is fairly 
improbable.
