Yeah. I honestly think you have to legitimately like the rodents and rodent care to be able to make it at all worthwhile for any but the biggest snake keepers; the pain in the ass factor is high.
I wouldn't mind having and breeding mice or rats and having the snakes eat the culled babies from litters/the breeding program, but I'd never be able to do it as the sole means of feeding my snakes. I just don't have enough snakes to make it worthwhile, and I don't really want to breed on any kind of scale or regularity. I just happen to like rodents along with reptiles.
