Nick, Alan, what is your take on these option names? Having dropped the 's'
from the original form is an improvement imo, but I'm a little afraid "info"
(unlike "warn") may become ambiguous with something else down the road.

In all of the doc changes you appear to be entirely ignoring the present
alphabetical sorting in the blocks you insert into. The info additions
want to all move further up; the sorting there isn't on a "related to one
another" basis afaics.

This change will need explicit buy-off by Arm64 folks. Mind me asking why
you Cc-ed only Richard, but not Marcus?
