Hey there. As I mention in my blog post, there are still remaining issues that we are aware of and will fix. We got some consultancy on the remaining accessibility issues, and they were graded with priorities. We took care of all the ones that were flagged as blockers, and are working through the rest of the list over the next three months. You can track progress if you are interested in https://phabricator.wikimedia.org/T318373.
Some of these are made a little more complicated as they involve different teams - for example the language button is owned by a team who works on a Asia/Europe timezone (compared to our US/Europe timezone).
Hey there, developer here and I can confirm that we are still actively maintaining those skins and preserving them. We have around 101 skins that work with MediaWiki and 7 skins deployed in production.

I think you are specifically referring to https://phabricator.wikimedia.org/T325009 (still awaiting discussion) and https://phabricator.wikimedia.org/T318013 (resolved next week) ?
