Yes, I think this is absolutely fine and consistent with the OM changes
we discussed during this week's conf call.

Please note that we have a similar problem when we climb up the cascade
to, for instance, tweak the styles attached to selector "p". The rule
responsible for the styles can have in fact a group of selectors, and
it's then up to the editor to detect it and split the group of selectors
to result in several different rules. Nothing new here.
