Some developers look at language specs, so spec position does provide meager
influence that way. Documentation authors are the likelier target. They're
going to look at specs to figure out what the methods do, to a much greater
extent. Positioning in Annex B and not in main flow sends a small message that
something's different. MDN documentation of octal syntax, for example, is only
found in a deprecated/obsolete features page, for example.

Yup. Everyone writing for the public non-mobile web has to do it now, it's not
so bad.
