Well, to be honest, I'm not out to breed hard to breed shrimp necessarily. Amanos are pretty common and as far as I know will continue for a long time to come.
I guess I'm thinking that there are some animals that are really functionally extinct in the wild that have only been kept around through the hands of hobbyists. Ie. Syrian hamsters, etc.
There are already species of shrimp that are extinct. Perhaps we can make some small form of impact as keepers of shrimp to keep another species going- even if in an artificial environment.
