This seems to require that the specifications be available as something
"patchable" (e.g. GitBook source code), and offered in some public git repo.

How does this play together with *patches* for specs (see above)?
Attaching patches to BZs is not good practice. Should we attach complete
renderings of the patched (huge) specs?

Sounds good to me in general.
I think we'll have to work out the nuances of the coding style in
practice, while actually developing such additions. I can't name
anything specific that's missing from the proposal, but I'm quite sure
we'll find corner cases in practice.
Thanks
