Right, with Ukraine being supplied primarily by relatively untouchable (without massive escalation) NATO countries (and no end to that supply looking likely), the "total war"-style strategic bombing isn't really a meaningful aspect. Additionally, killing large numbers of Ukrainian civilians (by conventional or nuclear bombing of the cities) would be crushing for the "liberating our people" narrative that Putin has relied on so far for support from the Russian people.
