@oconnor663 based on discussion here, and the BLAKE3-team/BLAKE3#68 I've updated this patch.

Moved the notice to the Modes section. Specifying that the same OID applies to all modes, for the default output size of 256-bit. Which matches the description of the previous sections which define the default output size.

Or do you want to drop the 8, and then simply use 1.3.6.1.4.1.1722.12.3 as the OID?
