Both are valid, and it makes sense to be clear about what the teams view is
I think the confusion of bug tracking with work tracking comes out of the bad old days where we didn't write tests and we shipped large globs of changes all at once. In that world, people spent months putting bugs in, so it makes sense they'd need a database to track them all after the release. Bugs were the majority of the work.
But I think a team with good practices that ships early and often can spend a lot more time on adding value. In which case, jamming everything into a jumped-up bug tracker is the wrong approach.
