I must have misunderstood your question as taking care of live shrimps is part of the joy of the hobby. Changing the water is a perfect time to observe your colony's coloration, health, density do you have any culls etc. Trim some plants, get rid of some algae... Maintenance can be done in 15min per week so not a big hassle.
Otherwise, you can just put these somewhere and forget about them. They will be okay for a long time. They even come in colors:
Do you have any concerns regarding hitting the exact water parameters or ?
If you plan from the start to ignore a tank, maybe it is better not to set it up. On the other hand, if you look around you will see that the harder it is to breed/keep the shrimp the more sought after they are ( often higher price), thus low grade RCS or ghost/feeder shrimps might be what you are looking for.
