A lot of what the "1500 hour rule" did was to make airlines "take back" ATP-level training and certification, rather than going out and doing it in a seminole with a DPE. All of a sudden, most people had to go to the airline to get the CTP course and then took the ATP checkride during their training there. The only deviations issued for the simulators are for weight differences that are "close" and an airline that is already using something that otherwise meets the requirements. Who has these simulators? 142 schools. Who was intended to conduct airline training when the airline didn't have the resources? 142 schools. Yes, there are places out there that offer the course that are not airlines, but by and large, the rule has made the airlines "take back" this level of certification and training.
