agenda+ Labeling tracker issues for specdev

I've been adding labels to 
https://github.com/w3c/i18n-activity/issues?page=5&q=is%3Aissue+is%3Aopen 
that correspond to specdev section ids (and some with -x that we don't 
have specdev sections for but probably should have).

This provides a way of finding related issues.  It also helps us 
identify where we need to add stuff to specdev.

If we then also add links from the specdev sections to lists of related 
issues, that will help developers find how others have addressed the 
requirements and point everyone to useful details, beyond what we have 
documented in our articles etc.

It should also be useful for people doing reviews.

Any suggestions about how to implement this?
