Waste management has always been a purely political problem, since breeder reactor designs have existed as long as enriched uranium fission reactors. Most of the waste of breeder reactors is radioactively inert; the problem is that mining uranium is profitable in itself, and it probably shouldn't be.

My understanding has been that an additional reason breeder reactors have been discouraged is due to nuclear proliferation fears; the neccessary reprocessing of the fuel also produces weapons-grade plutonium.

proliferation argument doesn't hold considering you can do it much cheaper with distributed enrichment of uranium. Breeders can open a pathway for plutonium warheads but it's more about optimization. If a country wants such warheads, it'll start with easy enrichment path
