I've never worked in an org where this would be necessary but I can see the use case. If you only want to give your designers building blocks and expect them to use them only, then preventing detach makes a lot of sense.

If there's any flexibility in your designers' work, though, preventing detach would be very frustrating: to create a new thing we'll (designers) often pull from an existing component and detach it in order to harvest it for parts. Not being able to do that would drive me batty.
