This would be very helpful. Another example of an extensibility section (work-in-progress):

With the above guidance on extensibility, developing new functionality separately would allow these extension specs to be consistent with the core and among themselves, which would make merging them back to the core less of a chore.

I assume a new version in this context refers to a TR publication?

I can see the concern of spreading resources too thin. If we had its own editor(s) for the rec-track and nightly branches this might work -- but I think we're not there.
