Then perhaps there should be a prompt escape for the keymap? The letters
'z' and 'Z' are not yet taken. (I hate requiring PROMPT_SUBST.)

This still requires one to write
zle-keymap-select() { zle reset-prompt }
zle -N zle-keymap-select
because the ZLE parameter set is only installed for user-defined widgets.
There's probably something more clever that could be done, particualarly
with ZLE_STATE and with the conditional. The above is just an example.
Incidentally you have to "fix" the keymap name etc. in zle-line-init as
well as in zle-keymap-select. Maybe zle-keymap-select should be called
just before (after?) zle-line-init, since the keymap is initialized at
that time.
