yes convicts are only good as feeders up till around 1.25" then they develop those hard spines, before then they are good as anything for feeders.
It is also much easier/cheaper/faster for large breeders to get feeders out of guppies and goldfish. Huge ponds full of guppies can produce LARGE amounts of feeders quickly with almost no food dumped in, most of them live off of plants and insects.
