And as someone mentioned, these other distributions have long great 
record of system upgrade from one release to another. CentOS has no 
record (and probably no upgrade engineered yet). In that respect CentOS 
Stream is way behind Debian (and clones) LTS. Not to mention other 
potentially problematic areas as no package version rollback, 
compatibility (potential) with EPEL, and other things I don't what to 
attempt to think about. As everything with newly architectured 
distribution which hasn't proven itself during long time suitable for 
specific things.

No disrespect intended. To the contrary: GREAT THANKS to hard working 
CentOS team for all your past work! And best wished to establish 
viability of absolutely new - and different - distribution: CentOS Stream.

And while people still ask and the list still tolerates, I will mention 
the system I fled my servers from Linux 6 or 7 years ago to:

FreeBSD

On average update requiring FreeBSD reboot happens as rarely as once 7-8 
Months (Linux on average every 45 days: kernel or glibc security update 
--> reboot).

Good luck everybody who didn't arrive at final decision yet to find you 
way for the future.

Thanks again, CentOS team for the great system you gave us for decades 
up until now!

In that respect, CentOS Stream is identical to CentOS.

CentOS Stream will be compatible with EPEL to the same extent that new 
point releases are compatible with EPEL.

The vast majority of interfaces in RHEL (and Stream) are guaranteed 
stable within a major release, and only a small number of interfaces 
that aren't.? It's possible that one of the latter interfaces might 
change, in which case you'd expect yum to not update the dependency 
until EPEL's packages have been rebuilt:
