This is so disappointing. The only new option is to allow teachers to manually create courses "anywhere they have active enrollments"? (the other selection is the same as having the feature disabled entirely, so what's the point of that selection?) This completely ignores the concerns expressed here that admins need some ability to indicate which sub-accounts can (or cannot) be used for manually created courses.
As others continue to point out, enabling this feature opens the door to SIS sub-accounts intended only for official courses, which effectively renders it useless on our instance, in my opinion.
This is one of the fastest turnarounds I've ever seen of a proposed Idea to deployed feature. I applaud Instructure for their attention to the community, and the prompt introduction of the suggested feature. But for goodness sake, please listen to the feedback from users along the way, or it's all a waste of time.
Thanks @robotcars for the link to the "new" idea to make this feature more useful.
