Problem:

A developer who actively follows specifications issues was not aware of a potential issue with a specification.

Description:

I actively follow the repositories of specifications that I'm interested in such as Fetch, webRTC, and ServiceWorker as to read issues with the specifications and any new proposals.

I only found out today about this repositories existence due to a colleague who is in the TAG and asked for opinions on the Fetch API "WithCredentials" flag issue.

Proposed Solution:

If a specification already has it's own repository (on Github or similar) which can have issues created, create an issue in it's repository about the potential issues found during a spec-review. I imagine it would get more community involvement as developers who are interested in the spec may be watching the repositories issues.
