Fair, but I'd prefer to not adapt too many of the surroundings yet.
Otherwise I fear that it'll open a can of worms that we can otherwise
address over time.

This one remains valid even with the new terminology. The loose cache is
specific to loose object files, which does have an associated object
directory. Refactoring loose objects to become a bit more self-contained
will be one of the next steps after these refactoring land.

Probably rather "loose object directory", as it is again specific to
loose objects.

That reads better. I'll extend this even further to give a bit more
context around primary alternates.

Same here, I'd rather not touch this comment for now. We'd only catch a
small subset of outdated comments anyway, so I'd rather focus on the
required changes given that this patch is already quite large.
