So rather have a white / black list?

Could we have a pre curated list with the list easily changed by the user?
So instead of screaming at the mailing list they can work around easily,
and eventually someone fixes the "stupid" default?

Maybe a user would want to do

    git config --global submodule-credentials-filter-white-list "host.*"

instead? (Naming intentionally bad)

I thought about that for a split second, but no. I mean it in the
most general  way possible.

It doesn't even have to be a submodule related thing at all.

I can imagine that `git gc` could learn to walk nested repos
(not submodules, just repos on disk inside the work tree).
And for that use case we'd maybe want to have a setting
to pack the nested repos more aggressively than the toplevel repo.

(Not sure if there would be a use case or such a thing, but it is the
first I came up with)
