Yes, that's why I said "principles", not "rules" or "practice". I
think the same principle works when Bach uses 9/8 in one part, 3/4 in
another (e.g. Jesus bleibet meine Freude in BWV147) or 12/8 in one
part, 4/4 in another (e.g. Mein teurer Heiland in Johannespassion).
But it's definitely not extended to multi-measure rests, as the
examples above prove.

Oh, these are all great!

as follows:
With measures longer than two whole notes LilyPond chooses different
glyphs for MultiMeasureRest.

According to Gould LilyPond's default seems to be correct.
Werner objects.
At least there's need for discussion, I think.
Attached an image showing "LilyPond's default" vs "Correct?"
