The vast majority of users don't care about this. And even if they did, it's not like there's any real competition in cellular carriers, so there still wouldn't be incentive for carriers to implement this.
On the flip side, there is lots of demand from law enforcement for them _not_ to. Law enforcement uses stingrays and would certainly pressure carriers to not implement something that stops them from continuing.
