This seems uncharitable. Priorities aren't exclusive, especially at scale across large engineering orgs like GitHub. It could be that these are the top level priorities, but teams or individuals who aren't able to contribute to these priorities will work on other things like new features.

Ditto. I agree though, just because the priority is reliability, doesn't mean others can't work on features, especially features that might help with reliability, which I read was the motivation behind the new single-issue view, so that's my bad, might have been a bit much.

I still think the rest of my point stands, especially the last one which is the move that has the biggest impact to the most of us developers.
