Just came across this mod, truely an awesome idea.
Is it possible to load this only serverside with the higher=faster feature, while loading clientside provides the cloud functionality?

Oh excellent!
I hadn't yet installed it on our dedicated server, i just read the modrinth page requiring it on the client side and posted this question. I'll be installing this now that i know it's not strictly required clientside, cheers!

Hello! Thank you for trying out the mod.

I'm not quite sure about the meaning of your question, the higher=faster behavior already works only server-side, and the cloud functionality only works client-side.

This means that flight settings will always affect all of the players on the server while cloud settings are independent from each player; although you can still play in singleplayer and flight settings will be your own because all worlds run on an internal server.

For the mod to work on a dedicated server it will need to be installed on it.
