For now yes, because the process isn't entirely automated end to end.
Given it's a step forward from the old situation of tough luck if you didn't have the skills to compile for yourself I don't see it as a show stopper, merely a limitation.
If there is a demand, it can be advanced but if not, and this is the first time I've seen it raised I don't see a direct need for it.
Can you point to those not having an autobuild from before the release, I'd be interested in finding out why they were missed.
