Adding a topic to roadmap or high-priority etc

The immediate example: @davidak suggested that supporting SEPA is a big deal to unblock European pledges (and European-based projects?).

So, this isn’t on our roadmap yet. And the issue isn’t well-groomed (added the needs-grooming tag though). It seems we need to capture some concrete tasks around studying the issue, recruiting help from those knowledgeable about it etc.

How should we generally manage marking priority tags and adding stuff to the backlog of the roadmap? I didn’t want to do this unilaterally.
