Eh, as a dev with family in real estate development, I can see why it hasn't. Zoning and building codes alone seem like an enormous impediment to scaling anything there.
Which I also don't understand as it seems like more trouble than it's worth sometimes (I worked for a corporation that was in that field at one point, we were expected to make big changes almost every year when new laws got passed).
A town of 10K might have a completely separate building code and zoning categories.
