    I would prefer :wait that defaults to t.  Is shorter and avoids the
    negation.

A default that isn't nil, when nil cannot stand for use of the
default, is problematical.

    Hmm... this looks a bit strange.  Can you give some examples?
    Especially, what do you supply as VALUE?

That usage seems like a kludge to me.  What exactly is it trying to
solve?  Would it work to simply try this combination of args, catch
the error that you get if it isn't supported, and try another method?
