Absolutely. I have three tanks and maintenance is really only tidying up the plants and keeping on top of the water. Between the shrimps and a few nerites I have barely any algae so there is very little to do.
I have a UNS 60u that is shrimp only, we do weekly WCs along with the other tanks but that is because we have a system to do all the tanks at once. I think that a shrimp and snail tank is really easy to maintain particularly if you don't have any stem plants. Moss, carpet, crypts, Java Fern, etc., all work really well in a low-maintenance tank.
IMO shrimp only tanks still need periodic water changes. It will certainly not be drastic as requiring 50% or more water changes every week.
My shrimp only tank was low tech with only some easy plants and I used to do about 20% water change every 2 weeks. Some times more than 20% but the two week duration was to ensure that shrimps have enough time before their molts.
I do about 30% weekly change on my no CO2 shrimp tank, and quick look over + glass rub with toothbrush as needed. Filter clean about every 6 weeks. It’s easy mostly because it’s small I guess and well established - only 20 litres.
