I think it would be fine to skip the IRC discussion (for Requests for Comment review) that would happen on Wednesday, May 7th, because so many potential participants will be in transit to Zurich. You are, of course, free to schedule your own meetings to discuss things, if you disagree. :-)
So, I'm seeking out proposals to discuss ~May 14, 21, and 28. Feel free to ping me personally or set something up linked from https://www.mediawiki.org/wiki/Architecture_meetings . Some suggestions: Content API, Knockout, Storage service, Clean up URLs, URL shortener, Json Config pages in wiki, API roadmap.
