The reason for this is that commercial adoption happened with PWRs and after that the nuclear companies had no need to commercialize anything else.

By the time Breeder research by government was happening the anti-nuclear movement of the 70/80 was already in full effect and research money was being cut and very few nuclear plants were being built so there wasn't much reason invest in commercial breeders.

Specially because fuel isn't that expensive in the first place and waste isn't actually a big problem either.

There are still other good reason to create breeders and if we are gone develop next generation reactors, we might as well go in that direction.
