 There may be other possibilities.

What about the existing pitch-repeating functionality in LilyPond?

\version "2.22.0"

foo = { 4 4 }

{ b'2 \foo g' \foo }

A duration without pitch is encoded as a NoteEvent with the pitch 

property.  expand-repeat-notes! is the internal procedure that carries 

over the most recent pitch.  So long as you insert these events early 

enough, LilyPond should do the heavy lifting for you.

You are correct: I invented a problem where none exists.

I confess that I had not realized that a duration without a preceding pitch or rest takes the pitch of the preceding note.  I actually thought that, following a rest, it would produce further rests.

I must have seen this in action many times, otherwise I would have lots of pitches in my music where there should be rests.  But somehow it doesn't seem to have lodged itself in my brain.

Perhaps I'm getting too old for this!
