That's true, but the OP's and my experience is that the adjectival use, like "woman doctor," was pejorative. I associate it with Greatest and Silent Generation relatives. We changed to say "female doctor," as it sounded more neutral.

Now, there's a movement back, and lots of younger folks now say that the latter is demeaning, and that "woman doctor" is the respectful phrasing. I know it's essentially arbitrary, and defined by usage, it's just interesting to see the evolution.
