    > That would be a slowdown in very important cases.

    Finteractive_form takes an absolutely negligible amount of time.  So I have
    no idea what you mean by "a slowdown".  The only "problem" I could imagine
    is that Finteractive_form allocates a Lisp string whereas the above code
    doesn't.

Sorry, you're right about that.
