Yes, beaming patterns for the two different, IMHO identical compound
meter notations should be unified.

I think that the maintainance cost would be zero – we just have to
announce the change, together with a generic warning in `convert-ly`
for all (A + B)/D meters that beaming patterns have potentially
changed.
In case my opinion is not shared by others – folks, please chime in! –
we have to improve the documentation, explicitly mentioning that
beaming patterns for (A + B)/D and (A/D) + (B/D) are handled
separately.
