For shared/non-shared stems that would not seem to fit the current
logic.  Mind you: for piano music the rather rigid relation of stems and
slurs and noteheads with voices is a problem.

So changing this seems attractive but it would be a very fundamental
change.

This hints back to the broader topic, of what are the intended uses of the
grand unified partcombine. (And whether or how many of these are captured
in existing tickets.)

While it is ideal to design to handle all cases including the most
complicated, does anyone typically combine piano parts?   What is the
musical use-case for this?

Or, putting it another way, how general is the issue of the "rigid relation
of stems and slurs and noteheads" within parts that people will want to
combine?  My hunch is that they don't much overlap:  if you are adding
rigid structures, what makes you think you should be able to automagically
combine something with it?
