It's all the talk of SIGs and developing and testing and that Stream
will be the centerpiece of that. That's what I meant.

I don't get that from the documents released today.  If Stream is *not*
a test-bed, then surely the code that appears in Stream must be fully
formed in secret behind the scenes first. Yes, it will appear piecemeal
rather than in one big chunk, but it has been categorically denied that
Stream is not a RHEL 8.n+1 beta and is more a RHEL 8.n+1 RC/rolling

I think what a lot of people are concerned about is the rolling-release
aspect of this. There will be no definitive versioning of CentOS in the
future - all you will be able to say is "fully updated" and it won't be
possible to slot a CentOS system in to exactly match a RHEL version.
Will third party RPMs built against RHEL 8.x be installable on a CentOS
8 Stream system? The answer is surely "it depends", but there are a lot
of hardware vendors that target drivers to RHEL releases, which may
well make CentOS non-viable for hardware that doesn't have drivers
built in to the kernel.

I suspect that for a large proportion of scenarios Streams will be
perfectly OK. But we still get software/instruments that specifically
say "only RHEL 7.4" or something like that (yes, it's a support
