I was making a point that the automatic mapping solely for the
menuselect case is actually available – despite being probably not at
the level of quality and design that we would expect from it – because
the complist module does automatically get the calls if they're done
on the menuselect keymap. So to solve the particular issue with
non-overloadable menuselect widgets what has to be done is to provide
the rest of the Zle widgets – to give them meaning in the menuselect
keymap, so that there's no risk that user's overloading widget will
call something's unimplemented – the Zsh script code isn't a threat
here, only the dot- i.e. original zle .widgets are.

I wonder if the enabling of overloading of the menuselect keymap
doesn't break the backwards compatibility. The "always leave
menu-selection" behavior, for example, will be changed by it. An
configuration option, rather preferably zstyle, could be used to guard
the compatible behavior (BTW. are zstyles used to influence Zshell at
the C level currently?).
