Make hitting the lava surface deal fall damage (MC-276989 fix suggestion)

Irl lava is very dense so falling onto it would be like falling onto a solid surface.

So how about making it so that you take fall damage when hitting the lava surface? (but not when you hit the blocks under lava so you don't take fall damage twice)

This would be realistic and it would make lava behaviour consistent no matter the depth (if MC-276989 is fixed the boring way, 12 block deep lava will still always remove all fall damage due to slowing you down)
