Obviously introduction of IRS has lead to it alot , but then again it comes down to manufacturers and commonsense.
It makes sense that both rear and front wheels be adjustable , when accelerating and braking the alignment changes , and also as bushes and componants wear down , but have yet to need replacing , wheel alignment is slightly off. Having fully adjustable front and rear allows to keep the car with a optimium alignment for handling and safety at all times.
Some of the older cars I have worked on , even ones that had IRS did not have any adjustments at the back wheels , and only toe at the front. My cars has rear camber adjustment and front toe adjustment , all the rest are preset from factory with the bushes and control arms ect ect , but as the bushes wear my alighment will move out slightly unless I replace bushes.
However the new cars I work on , have lots of goodies , like 5 link rear suspension setups and castor , camber and toe adjustments on front and rear. It's mainly due to progress of technology.
20 years ago it was easier to make suspension systems with factory set alignment on everything but toe at the front. Now days totally alignable systems are easily and cheaply manufactured onto lots of models of cars.
