The problem is that it's not the fault of the implementation.
The idea of having it as a function is fundamentally flawed, which is
why the function can be nothing but a mess.

`called-interactive-p` is in the same category as `advice-add`.
It's great that we have it, but you should only use it when there's no
other way.

Maybe they're kludges, but at least they have a well defined meaning.
`called-interactively-p` is in a completely different category of kludges.

Emacs is not in the business of imposing The Right Way, instead we
prefer to encourage it while still allowing people to shoot themselves
in the foot in all kinds of fun ways.
