So what is the thought process that's lead to infinite height being so widely adopted? There's no particular precedent for it in the rulebook. Doesn't it pretty much make hull down defunct? Or does it neatly solve a bunch of problems? Or does it just make it easier to play with squares of card representing terrain?
It is a very common UK wargaming convention for smaller scale games (2-15mm). As models are abstracted (the base size is key, not the models on it, for example 3 bases of 6 men each is a battalion of 600 effectives.
The squares of card are indeed fairly common as well

Been using them for as long as I have done 6mm WW2 (umm, 2 decades now? Yea gods).
It allows you to mark out an area of terrain and then you shift the buildings around inside to help bases of troops move through.
And of course, it is not really infinatively high, just so high only skimmers, flier and artillery can fire over it, and jump pack leap over it

It also saves us from having to model terrain properly.
I could do TLOS if the ground scale matched the model scale, as with a skirmish game. However if you want to play TLOS, you would have to concede you are playing in a battlefield 0.35 miles by 0.23 miles - assuming 1mm = 1 foot as per the model scale. Or 1829 feet by 1219 feet. And that our hills are 30 foot high etc.
