That is up to the map designer, I think? In any case, I've made some of the rocks bigger.

I'll merge this in a few days, if there are no objections or CI failures.

Looks good, thanks. Sorry for commenting without checking these in the editor first, having tested them it's easy to distinguish a line of these from a line of the flat terrains Cobbles or Cave Path.
