Annotation for issue number?

Would it make sense to add annotation with the issue number whenever
there are any changes made to the spec text. I think it will make it
easier for the TC members to understand where each change is originating
from. If a particular change is purely editorial, we could say that in
the annotation.

In my experience with other TCs, such annotations are quite useful
especially when the drafts include changes for many issues.

Thanks,
