From our CFI's Anecdotal memories after some 60+ years of flying, from starting in an instructional capacity teaching students to fly Mustangs in 1946 to currently instructing in a Jabiru (yes he is that old) "The problem of training students to handle crosswind landings only occurs after you have informed same of the fact that there is a crosswind. In previous landings by same student performed in a crosswind, said landings were executed with aplomb" .... Food for thought there!
