"interactive-only" should go far beyond a byte-compilation warning.

I suggest that "interactive-only" does actually make the function work
in an interactive-only way.  That would be much more useful, particularly
to users writing their own functions.  Currently the "interactive-only"
leads to quite some confusion.
