You theoretically could, but it'd be a bit awkward in places. It's not
hard for a small textual change to result in a large visual change (eg
if you use relative notes and add/remove an octave shift - it'll shift
every subsequent note in the staff, which might mean more/less ledger
lines needed, which will affect how much vertical space the staff
needs, which will affect pagination...), so it'd often make for rather
nasty flicker. Better to keep it explicit.
