In 2/2 splitting up the beams sub-beat is just wrong. Now we have the
"unless subdivided" moniker here and LilyPond should likely do more in
_that_ respect. In particular when beaming over several tuplet groups,
a subdivision corresponding to the number-carrying groups seems pretty
much mandatory to me irrespective of whether one uses binary subdivision
schemes (which I often find overdoing it) elsewhere.

For subdivision, yes. But splitting beams completely inside of a beat
does not make sense automatically since we are then talking about a
judicious breach of rules, and that really should be done manually.
