Remove exclusive: false

[basil]

At the time of this writing, 67 out of 507 CD-enabled components (13%) have exclusive: false. There isn't a real use case for this, so most (if not all) of these represent technical debt of some kind—typically a failure to complete the process of CD enablement and release a version using CD; because if that had already taken place, then I would have enabled exclusive CD in #3877.

These should be systematically evaluated; if CD is enabled in the plugin repository but a CD release has not been performed, then a CD release should be performed (in which case exclusive: false should be deleted), and if CD was never enabled in the plugin repository, then the attempt to enable CD should be completed (culminating in a CD release) or CD disabled for that plugin in this repository.
