I think some people have short memories, there have been numerous grumblings (right or wrong) about many of the step-change releases. To me, this feels a bit like when the rosetta fat-binaries were killed off in 10.7, for some people it was pretty bad for those with software which didn't and wouldn't support Intel binaries, but for others it was a minor blip.
Catalina has been fine for me, but I probably have a different use-case.
