It depends. How much does it increase memory use and/or file size? In general, 
having an eyeglasses and a Bartok pizzicato symbol might be useful (we've had 
several questions about the Bartok pizz, so that is really used in scores).

Both symbols should be fairly easy to implement in metafont:
-) The bartok pizz is just a circle with a vertical line (length is twice the 
radius) from the center upwards 
-) The eyeglasses are just two circles, one half-circle (the bridge, shifted a 
bit upwards), and a line plus a Bezier spline for each of the temples.

Not that I'm aware of. At least the MusicXML spec does not use any other tags 
which might use new markup symbols.
Thinking of it: Maybe the harp pedals (see attached screenshot from finale) 
might use glyphs, though. I've thought a little about implementing them and 
it would be much easier if I chould simply use a string that is automatically 
displayed as a harp pedal (e.g. \harppedal #"^v^|^v-v"). On the other hand, 
one can also implement that similar to the fret diagrams.

Cheers,
Reinhold
