If they would stop with the face reveals it would make this sort of screw up easier to manage. Kang rarely, if ever, takes off his mask. The High Evolutionary never takes off his helmet and yet did in GotG 3. Any appearance by Doom is likely going to get the same deal, just like it did in the first two films despite the fact he already put on the mask in the first film.
That combined with all the other stupid decisions make this a problem of Marvels own making
At least they got lucky by casting him as the most replaceable villain in the entire Marvel comic universe.
