Could perhaps a more generalized "Quality Fluids" mod be made, where all fluids that use quality ingredients can follow the same pattern as this?
Thruster Fluids, Electrolyte, Hot Fluoroketone (when making it), Coal Liquefaction, etc. to name a few.

Its a shame there's currently just the one extra entity for literally just one fluid when there could be many more.

i believe there's such a mod already out there

So there is, apologies, I had in my head there wasn't one. 😅

yeah it got created after this one i believe, its good for all those other usecases, this mod excels at the holmium usecase specifically.
