Cool, I understand where you're coming from.  If the world remained static
after this announcement I would be more concerned about this scenario.  As
it is, we're in a dynamic space, and CentOS Stream will be a place that
hardware vendors can participate as well.

It's certainly a change.

RHEL is developed according to a schedule that keeps us delivering minor
releases on a 6 month cadence.  That includes a period of time when we're
putting the finishing touches on one release and simultaneously working on
the next.  Folks on the CentOS Stream team can speak with more authority on
what the intended alignment points are (I know what makes sense from my
perspective, but there may be other considerations I'm unaware of).
