In a comment on your water mod compat fix mod, you stated that you were now using this mod instead. I thought perhaps that meant this mod superseded the compat fix mod.

this adds its own blocks, they do different things

I am a bit confused about which mods to use with Industrial Overhaul + Water mod. If I use this mod, do I still need the IO water compat mod and the compat fix mod?

does this mod stop atmo thrusters from working underwater?

ok

This needs to be loaded above the required mods

Any word on load order?

We should be able, I will put it on my list.

Could there be a non-Industrial Overhaul version? (Maybe using hydrogen instead?)
