AFAIC it's a limitation.  We could support interactive specs, but I'm
really not convinced it's worth the trouble.  If using 2 functions (one
generic and one interactive, which calls the generic one) is really
annoying for some reason, I guess you could use

    (put '<GENERIC> 'interactive-form <FORM>)

but I think this property should be deprecated, so don't tell anyone
(especially don't tell me) that I even mentioned it to you,
