More navigation the better, especially noting the potential for clutter certain team files can likely get in the future, and again, genuinely, there are no downsides to it other than you conflating "standard" with "clutter" based off really weak reasoning.

A literal line doesn't break standard. If anything rejecting this, you're creating a LACK OF STANDARD, because it means I have no definite place to list teams, and can very well link them between 5 different fields due to your utter vagueness
