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.
I guarantee you it's not preferable to the majority of github users.
Can you actually show us this research and a/b testing?
Except there was a different comment from someone that actually knew how it came around, and it was an ugly performance workaround.
> A/B testing showed github that this might be preferable
A/B testing can’t measure preference, only interaction.
