Apple not keeping legacy cruft is why they were able to move to ARM so quickly. For all the grumbling about cutting 32-bit support couple of years ago, this is what allowed them to do that (among other things). And, as demonstrated, developers like Valve take action only when they are forced to. Windows and Linux on ARM are stuck in the mud with no end in sight while Apple is almost done with the transition.
