Hah noted! I appreciate your arguments. I was thinking about testing a ritual room that applies to adjacent rooms so not per room but you can create clusters. I think overall research will stay at one room, but may have some form of room that can boost research speeds (with research getting more expensive and a little slower, as you can unlock a lot in a row and loose track). Rooms may be tested with excavations and a build menu to limit the amount of UI you are clicking on with machine upgrades being removed in favour of global machine tier upgrades. so its more about your factory layout and rooms rather than machine micro.
But just a few ideas I have swirling around my head
