Is that always the case? Jungles are never grasslands when you clear them?
There's a few region maps where some are grassland, but if it's a scripted map; it's going to be plains.

It's quite possible to check if a forest is grass or plains.
I think that the prevention of a Stone Works on a plains tile is to sort of keep these type of killer starts (with salt and stone) to a minimum.
