Hi folks,
A few months back, we switched to updating the WMF Engineering Roadmap in Google Docs[1], and deprecated the on-wiki version. This wasn't an ideal solution, but the way that we were doing updates before also wasn't working, so it was worth trying something else.
Now there's a script[2] to update this page, which we've used for a couple of weeks now. The page is here: https://www.mediawiki.org/wiki/Roadmap
The page is output as old-school subpage templates now, which isn't perfect, but has the advantage that there's a lot of latitude to reformat the page without altering the script. Feel free to play around with the formatting.
The next step I'm planning to take is to output the page as something that can be loaded via Scribunto's loadData call, which then will make it pretty easy to include portions of the output in other pages.
This isn't in Gerrit yet, but that's only because I haven't quite figured out where it should live. Suggestions welcome (offlist or on my talk page[3] is probably best for that).
Rob
