In December 2018, there was some information gathering about what could be improved in the profile pages and settings; the page needed to be adjusted to fit the responsive design in any case, so it made sense to see if other changes needed to made at the same time.
In March 2019 there was an update posted to Meta.SO. It detailed some of the information gathered, and mentioned some disconnects between how different groups of users used the profile pages and settings.
However, over two years after the initial post and quite a while after the responsive design was rolled out... that page still hasn't been made responsive:
(Note the white spot at the top right, which has been there since day one of the responsive design.)
Are there any updates on this project? Will we be seeing any updates on this besides the information gathering?
