Yes, this is a good suggestion, but one which'll be much easier to do
after this series. Since the majority of callers don't care about the
raw mode bits or anything except if the entry is a blob/tree/commit.

Indeed. This goes back to my "bear with me" comment upthread. I'm
planning to fix these cases too, and starting by moving most things to
"enum object_type" makes that a lot easier.

Right now we simply trust the mode bits, but that opens the door to the
same sort of bug I'm fixing in another series (that I need to re-roll)
where we have a "type commit" and "object ID" in a tag, but the ID is
really a tree or whatever.

We then get confused because we trusted the invalid metadata over
checking the type of the object ID we have in the object store.

So this particular series doesn't fix this bug at the end of it, the
"object_type" in tree-walk.c is just a function of deriving it from the
mode bits.

But once I've audited the cases where we're really just acting on the
type and don't have or use the mode (so we know we're not re-writing the
mode somewhere) then we would set the object_type to the actual type, as
in what we'd get from oid_object_info(ID).

Then we can e.g. scream murder about a mode/type mismatch in fsck, but
still be able to list/diff/inspect etc. that object in any codepath that
just wants to e.g. recursively iterate over the tree.
