That's true, but I think they can actually imitate the style of the fic they read and simply not use epithets as much because the stuff they're reading doesn't use it. You'll still, of course, see the common basic substitutions like "the other man" and probably "the blond" more often than I or another strict beta would allow, but they won't be spontaneously adding epithets for doors and windows and whole sentences as adjectival clauses into them.
