I should also point out that what I was planning to do was not hidden. I wrote about these changes in my weekly report the Monday before I committed them (http://bit.ly/cqAcqz) and pointed to the weekly report from my Ohloh, Twitter, Identi.ca and Facebook accounts.
Granted, this is not the same as posting to the mailing list, and for that I apologize.
Looking back in the archives on gmane, it looks like you are very interested in MW testing. Since this is a large part of my focus currently as well, perhaps we should coordinate our work?
Please coordinate through wikitech-l and the SeleniumFramework page on mediawiki.org [1]. It is good to broadcast information through other sources as well, but normal communication methods are best. If changes are being made to the framework, the documentation should also be updated.
