Yes: a zle-widget that puts the prompt below the list if there is one.
That allows me to keep the current list for later reference if I decide
that I want to.

That would be useful, though the widget would be better.
I couldn't actually get this to work. Even just putting
compstate[last_prompt]='yes' before the compadd in _complete_word didn't
work.

Out of interest, why does _setup use zstyle -s followed by [[ "$val" =
(yes|true|1|on) ]] for various things including last-prompt instead of
just using zstyle -b (or -t or -T)?

There's probably quite a lot of commands like zpty where they can be
used in a few separate ways (each with their own set of arguments) and
for these commands it is useful to avoid the final arguments for some
forms so if it is fairly simple to do and there is a clear way of
representing it in the _arguments parameters then it is probably worth
doing.
