Well, we have \omit already.  What if we had
\appearance [markup] [grobname or music]

Which would basically be the syntactic sugar for overriding the stencil
with an appropriate grob-interpret-markup?

That way one could just define some markup function for formatting time
signatures and use it either in markup contexts or indeed for overriding
a time signature.
