You are right.
Snippet #659 is a workaround that works in some case but your example
shows it fails with notes.

IMHO this feature (expand the whole measure, not only between two notes)
could (should) be implemented.

A workaround in this case could be to increase the length of the rests
measures.

  \override Staff.MultiMeasureRest #'minimum-length = #24

Result is better with "non-church rests":

  \override Staff.MultiMeasureRest #'expand-limit = #1

but that does not solve the feature request.

Cheers,
Xavier
