Named branches have a bunch of different semantics attached, though,
which I guess makes them heavier in some sense (e.g. the concept of
branch heads, which can be fairly confusing). I do of course agree
that named branches are not really heavier than unnamed
heads-as-branches in a storage sense.

I do suspect we have to be careful throwing the term "branches"
around; a branch could either be a clone, a head on some branch
(whether named or not, but usually only when there are more on than on
the same named branch in that clone...) or a named branches label...
