I also thought that would be useful earlier but now qcow2 overlays
provide much better flexibility and don't litter the commandline
syntax. I think the currently available choice between -snapshot (for
the simplest possible use case) and qcow2 overlays (for anything more
complex) is a perfect balance for usability and there's no need to add
more switches.
