I thought the whole idea of protected types is that they were designed
to prevent this type of mistake (either forgetting to lock semaphore
or forgetting to release it).
Also, I have read that implementing a semaphore using a protected type
isn't very efficient, as protected types weren't designed for this
purpose.

This wont prevent mistakes where you forget to lock the semaphore.
