This is a good argument for creating ly:grob-has-interface.  I only know
about grob::has-interface through stumbling onto it in an email.  A user
wouldn't know about it unless they saw that email from Neil Puttock (I
believe it was), saw some code inspired by it, or noticed it in
scm/output-library,scm, or wherever it is.   I've searched for it in scm
files a number of times, because its name is odd.  (I'm not even sure about
the two colons as I type this, but then again, my memory is bad.)   The
Scheme functions page would be a great place to see documentation for this.

I suppose even better would be to come up with a way to automatically
document public Scheme functions, but I wouldn't know how to do that at
this point.
