OK.

If you go to such an extreme and make readers oblivious to what a
branch means, some of the sanity measures we have (e.g., a branch
ref will never point at anything but a commit object, not even a
commit-ish tag is allowed) would become "unnecessary nuisance" to
them.  In other words, as I hinted, it takes a delicate balancing
act.
