What makes it easier is having fixed goals in mind, because I am seeing a lot of people in this thread arguing because they're all solving different problems which is obviously going to mean different solutions. If your only concern is passive tracking, then a randomized MAC being used for SSID probes (because whitelist-only hidden SSIDs are rare enough that those people can manually connect) will be sufficient. If you're looking to keep an open Wifi provider from tracking you over the course of days, then using a different MAC for each connect is going to be sufficient. If you're looking to avoid tracking by people doing traffic analysis to correlate by behaviour no amount of MAC trickery will help you. If one is looking to avoid having to pay for overstaying their visit at a coffee house or similar capture portal, maybe what needs to be changed is one's sense of ethics, and changing a MAC won't help with that. So, you can say "it should be a default" all you like, but everyone's going to have a different idea of what the default is for and they're going to throw a fit about it not being "the right default". Better to be conservative like Android and avoid inciting the newbs.
