There are entire segments of the industry that has never touched any javax package - while no doubt widespread, I do believe that it is still a very fair price to pay, and none of these changes were even half as problematic as for example the python 2->3 migration. So I don’t know, I’m fairly sure it is impossible to keep a platform alive with even less/smaller impact breaking changes.
