This title is misleading: yes, a bunch of users didn't liked it. But of course there's UI research and likely A/B testing showed github that this might be preferable to the majority of users.

Personally, I don't like it much. It sounds like leakage from AzDO design. Maybe a option to turn it off would be the best way out.

Disclaimer: I work for msft, although I've no connection to github, ado or any other such tool.
