I hate to be the bearer of bad news, but this feature request has been declined.
Very useful to build out Teams specific to different use-cases - controlling the Files tab is very useful for that otherwise it can cause storage location issues.

Agree with request - having users connect with he comms that Teams offers ahead of provisioning files (i.e.staging the two aspects of Teams) is vital
