Nice; your patch works very smoothly -- using `M-x' to switch here feels
very natural.

I think that can be fixed by refactoring out most of the interactive
spec of `execute-extended-command-for-buffer' and then reusing it.

A lot of people have `enable-recursive-minibuffers' bound, though, which
is an argument against using `M-x' as the keystroke to switch between
modes.

I think this use case demonstrates that perhaps we should slightly
un-deprecate initial-input -- instead of deprecating it, we could
instead just discourage the usage.
