Any reason you want to keep that restriction ?. FWIS, devlink is a driver api just like ethtool is. and ethtool needs to move to netlink soon...and It would be better to not put the rtnl_lock burden on ethtool driver operations. Instead of adding yet another driver api, extending devlink seems like a great fit to me.
