Correct. The spec is frozen, and public review is complete. Here's the tracking ticket for details: https://jira.riscv.org/browse/RVS-1111 I use the word draft because it is still an -rc version, but I can reword this if you prefer.

I just was double checking the state of the extension before acking the patch. It'd be good, in the future to note what the status is, given the policy is to not accept things that are at least frozen. Acked-by: Conor Dooley <conor.dooley@microchip.com> Thanks, Conor.
