OK, here's an unusual case ...

    alias safely:foo='[[ -n $functions[foo] ]] || foo'

    safely:foo() { echo this is foo only if no other foo }

I hesitate to suggest further convolutions, but maybe an option to the
alias command to "locally" switch on ALIAS_FUNC_DEF if it's actually
*meant* to be used that way?

Probably not very important.
