Hmmm, you've kind of stumped me. I don't have enough context to answer.
I just cringed a bit at the idea of having to edit a different kind of
file for setting
emacs variables. I suppose you would provide something like
add-dir-local-variable, but still...

Assuming my half-baked understanding of all of this is minimally
correct, I'd say "global" though. I might want to change my project
from make to cmake to something else and keep my list of ignored dirs,
right?

I wrote somewhere else that I think some kind of vision is needed
for the whole thing (a simple ASCII diagram would do for
me). Personally, I tend to like your approach and it seems to be modular
and simple, but I got lost in the details of your discussion with Stephen...

Is the general picture something like this?
