However, the implementation of the APIs that install protocols was done to make sure the optimizer produces the=20 smallest number of instructions to install the=20 protocols. I would prefer the APIs that install protocols remain unchanged, and that only the new APIs to uninstall the protocols be added. The same approach could be taken in the implementation to produce the exact right form of the uninstall action that is guaranteed to succeed if the uninstall API matches the API that was used to install.
