> As to how Lua should be labeled, I'm not too worried.

It's not so much about labelling as to how to improve Lua.

> At least there's no big disagreement

No big disagreement, but some such as John Belmonte and myself are
worried about confusion leading to an inadequate improvement to the
language. Fortunately, the Lua team seem to have got the message we
want them to get: allow function closures with assignable free
variables, accessible with the same syntax as local and global

All this stuff about lexical and static scoping has been a bit of a
distraction, the usual trouble with confusing arguing about things
with arguing about definitions. The latter is unnecessary: agree on
definitions, then argue about things.
