I fiddled with {{RFC}} to categorize pages without bug or task. Category:Requests for comment with no task shows
► Requests for comment (accepted) with no task (11 P)
► Requests for comment (in discussion) with no task‎ (13 P)
► Requests for comment (in draft) with no task‎ (37 P)
► Requests for comment (stalled) with no task‎ (6 P)
(106 RFCs supposedly not in Phabricator, out of 180 RFCs on mediawiki.org)

► Requests for comment (declined) with no task‎ (20 P)
► Requests for comment (implemented) with no task‎ (19 P)
(These archived categories are less important to bring to Phabricator.)

To harmonize, follow the process:

• triage the RFC
  • if it's completed then archive the page by adding status=declined or implemented to the page's {{RFC}} template
• locate Phab task for the RFC
  • create Phab task if not found
• add task=TNNNNN to the page's {{RFC}} template.
• you can use extrastatus=Some comment in the page's {{RFC}} template, e.g. to link to the meetbot IRC discussion summary
• move the task to the appropriate workboard column

@Spage, this task is marked High priority but it is not scheduled in any sprint. Can you update it, please?

@Spage, @Qgil: I think this is essentially done. Or are we missing any important set of RFCs on phab?
