They have, sadly, been doing this on MacOS for years. It was like that in the Classic days as well, they were always one of the few companies who actually used an installer, and cleaning up after one was an annoying process of combing extension and preference folders for lingering cruft. Fortunately there were apps to help find useless leftovers, but it was still a pain compared to how otherwise pleasant the MacOS software experience generally is.
