Indeed. I've thought about that a bit, and it's one of the reasons
why I was so reluctant to accept a relationship between pitch and
symbol which changes with the clef. Provided that relationship
is the same for both staves, having a voice move from one staff to the
other is not impossible.

If your grand staff is drawn with just one leger line separating the
treble and bass staves that's not too difficult.

I think they do so already.
I'm reluctant to make any further additions to mutivoice abc at the
moment though until we get a bit more agreement on the basics.
