On the other hand, if everyone uses the same non-transparent list of magic hashes to ban hosting images then censorship potentially becomes a concern.

If non-CP images start being blocked by this system, some gallery author is going to notice it pretty quickly and report it to the website owner. This censorship problem is remarkably easy to destroy the trust of the CP filter and I doubt people at Microsoft would fail to predict this.
