Pre-RFC: Deciding WG Focus

[jamesmunns]

We would like to have a stated process for deciding topics that require WG-level focus, similar to our previous "Wish List", seen here: #269 (comment).

However, we would like to do this on a more continuous basis, to avoid high goals.

We should discuss:

• How to nominate issues
• How to select from nominated issues
• How to triage, work, and declare items complete: either successfully, or by putting items "back on the shelf".
