If the world remained static after this announcement I would be more concerned about this scenario.

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). -- Brendan Conoboy / Linux Project Lead / Red Hat, Inc.
