To note, "this team owns X" still has the team justify a budget or even its existence when push comes to shove. For instance if there was a “blue check” team of 3 people at Twitter, they’d have a hard time justify keeping the team 100% committed to it for years after the feature is released even if there is some small amount of ongoing work needed. Looking at estimated output vs the costs, they’d probably hibernate the team most of the time, as you do with projects basically.
