The power is a very good idea. Maybe instead of maitaining it you can hook it into the new Mystical Mechanics API. Its pretty much is the rotational power using gearboxes. You could probally add the stone axles to register with that mod. and use the water wheel to use its api. If you do this, it might be easier to keep up with the code base. Personally i hate ExCompressum's sieving with RF. i find it OP. Atleast the auto sieve is automatiable but not easiely. The grinder would make it feature complete, and using Mystical Mechanics API might help speed the development

The code is here, the api is probally found in here https://github.com/DaedalusGame/MysticalMechanics

And the developer of Mystical Mechanics has said this

"the thing this system has going for it though, is that it has close to no baggage (no other machines, blocks or items)."

This was asked after seeing your Sifter Issue (automated sifter) and this PR #124

You could also make it a soft dependency meaning if you dont have it it doesnt have auto stuff but adding it gives you the automatic stuff

but to be fair the mod is very light

(would of edited the post but you get emails not check github so i didnt know if it would send)
