Thanks for forwarding, very appropriate to do so.
I note there was one line about this in https://www.mediawiki.org/wiki/Architecture_committee/2017-03-01: «The new MediaWiki team is up and running, with Tim Starling in the lead. There is a job opening for Product Manager for MediaWiki». I asked for more context on the talk page, but of course it's good if Wikimedia Foundation invests more in MediaWiki per se.
