It's basically fully functioning on the esp32-P4. But on hold for a bit while we focus on an update to close some vulnerabilities (nothing house-on-fire level but worth addressing).
I've been estimating that full code review on the esp32 work will take 6-12mo. We've always been very cautious and have moved slowly on purpose. But even moreso now.
That being said, everything is FOSS so some people have begun buying the hardware and running the experimental code.
