Restrict Waterfill to only Landfill tiles

I like the challenge of not being able to just place water anywhere. So no easy water pump placement or biter barriers. But if I enable waterfill to correct "mistakes" of lining up exactly where some bit of landfill needs to be in the middle of a lake, I'd like to be able to correct that error.

Would it be possible to have a "Restricted Waterfill" setting that can only allow placement of waterfill on landfill tiles? I suspect this would also require restricting landfill to water tiles as if I recall correctly Dectorio opens up placing landfill even over say a patch of sand.

I suppose the option is to just not place waterfill where I don't feel justified placing it. But it would be great to have it as a solid gamerule for any multiplayer maps.

Could probably add this under the "Waterfill tiles" dropdown setting in the startup options.

Thanks for considering!
