OK. Then I think rests.M3neomensural should be given the SMuFL name 
neomensuralRestMaxima, and shouldn't be an alternate of anything. (It 
seems like a bad idea that both the longa perfecta and the maxima are 
labeled with the M3 duration in LilyPond, when in fact they aren't 
interchangeable...)

Terminology gets a bit muddled around here. To clarify, are you talking 
about the glyph-on-glyph ligatures found throughout the SMuFL 
specification, or the note-on-note ligatures characteristic of mensural 
notation?
