Frankly, my own take on what that means would not have been to abolish
grace time: it's still useful for identifying things.  But rather to
reduce NoteColumn/MusicalColumn sharing/alignment during grace time to
being just per-Staff, or possibly as option per-Voice.  That would
allow, for special cases, to still blow it up back to being per Score.

One thing I find irritating about grace time is what it does graphically
and in midi to an appoggiatura.  Those are usually supposed to come
on-time, have at _least_ the nominal duration and steal time from the
_next_ rather than the previous note.
