These observations are greatly dependant on who is saying it: CentOS folks probably have a very different idea about stability than most Linux desktop users.
Either way, I always had the impression Streams concerns are exaggerated and mostly hear-say. There are better reasons for not using Stream, namely steering clear of Red Hat and not reinforcing their ecosystem.
If I'm allowed to muse, I never understood all these CentOS forks either. Why not put that effort into Debian, a truly democratic distro without any corp able to make these kind of moves?
