It's very late in the cycle, but I'm considering trying to squeeze
this into v4.9 on the grounds that:
- It's only a documentation change and can't break anything, and
- Distributing it more widely may help the arm64 firmware ecosystem
But I don't want to disseminate misleading or incorrect information,
so if it needs clarification or wordsmithing, or even just maturation,
I'll wait until v4.10.
The Consumer/Producer stuff, in particular, doesn't seem 100% settled
yet. Your thoughts, and especially your improvements, are welcome!
