Is the syntax you proposed really better?  Are you saying that you
advocate never using "#phy-cells" other than 0 for new bindings?  Is
that your own personal preference, or is there a discussion somewhere
where everyone agreed on this?

My vote is that since "phy-cells" exists and is part of the generic
phy bindings that it's meant to be used whenever you have a single PHY
driver that controls multiple PHYs.
