It just occurs to me that, since the refs directory structure of a
linked worktree is exactly like one in a normal single-worktree setup,
minus the shared (or packed) refs. The "files" refs backend can just
see this "per-worktree only" refs directory as a remote refs storage,
which is just another name for "submodule".
So, we could just use the exact same submodule code path in refs to
create a per-worktree refs storage. Doing it this way, files backedn
do not need to learn about linked worktrees at all. To retrieve a
per-worktree refs storage, we do
"get_ref_store(".git/worktrees/foobar")". To get all per-worktree refs
do for_each_ref_submodule(".git/worktrees/foobar", ...).
Does it make sense? Should we go this way?
