In uuid6/prototypes#2 (comment) you mentioned it would be an option to reduce the number of bits for subsec in case of v7 with nanosecond precision to 30 bits from 38 bits. Can I ask what made you decide to not include that change?

[kyzer-davis]

@nerg4l, I definitely plan to iron that item out with @bradleypeabody before a draft 02 resubmission to the IETF.

Once we have revised the text with better verbiage and pseudocode; I will open another PR just for the changes to 4.4.4.1. UUIDv7 Encoding

[bradleypeabody]

Thanks @kyzer-davis - looks good to me! Merging.

I'm also going to try to organize getting a page put together which shows these three different versions visually and breaks out the different fields into separate readable values, showing the encoding of each. I think it would be an excellent complement to the draft and make the whole thing much more clear and easy to wrap one's wits around when writing or maintaining an implementation.
