Brendan, can you clarify the following points?
- are you going to keep stable ABI between Stream kernel releases, or 
should we expect each kernel to break 3rd party drivers/modules?
- what/how many synchronization points are going to be with RHEL 
releases?
- what about security updates? Will they be released *before* the 
corresponding RHEL secure patch, or should we expect the (slow) current 
update cadency?
- is an upgrade path from Stream-8 to Stream-9 planned, or the usual 
"total server rebuild" will be necessary?

Full disclosure: the main CentOS point was to be 100% compatible, down 
to the specific kernel used, with RHEL. To get that, we lived with: a) 
comparatively few packages, b) not-working yum security-only updates and 
c) very restrictive selinux policies.

I am heavily invested in CentOS/RHEL ecosystem and I opened many bug 
reports/enhancement requests in the past years, so I would really like 
to continue using CentOS. However, using Stream seems to removing the 
key selling point (ie: total RHEL compatibility) without clear benefit.

Thanks.
