Wouldn't setup.c::is_git_directory() say "nope, you do not have a
repository there" if you are missing $GIT_DIR/objects? So I suspect
that the only case this matters in practice is a missing pack/
subdirectory.
I agree that silently ignoring missing objects/pack/ is perfectly
fine, whether we auto-vivify it when we actually create a pack.

OK.

This is called twice, with $GIT_OBJECT_DIRECTORY and its pack
subdirectory, as it does not recurse.
This is a tangent, I have to wonder how effective the first call
would be, though. When writing a loose object file, we compute its
object name first in-core and determine the final filename, create a
temporary file in the same directory as the final file, write into
it and then finally rename the temporary to the final name. The
fan-out $GIT_OBJECT_DIRECTORY/??/ directories may have temporary
files left when such a process crashed, but do we create cruft "git
prune" should remove in $GIT_OBJECT_DIRECTORY/ itself?
