Because in "git for-each-ref"'s "family", ref_array_item is generated
by filter_refs(),
which uses ref_filter_handler() to fill ref_array_item with ref's
data. In "git cat-file",
we care about the object, not the ref. Therefore, ref_array_item is
only filled with
{oid, rest} in batch_object_write() in cat-file.c. We cannot represent
some specific
ref-related data in "git cat-file", so we cannot have some atoms in ref_filter.
Yes, we probably won't support them in the future.
From an object-oriented point of view, the atom supported by
"cat-file" should be a
parent class, "for-each-ref"',"branch","tag"... they have more
specific object details (ref),
their supported atom should be a derived class, they can support more atoms.

Yeah. The sentence "because our objects don't have a refname." may not
correctly express the reason for rejecting these atoms. I will add
more descriptions.
