I am not a QFI (yet), but I was trained on Auster Autocrat J1s at a time when almost all PPLs were taildragger pilots, and almost all of our instructors were ex military pilots demobbed from a mainly taildragger airforce/navy/army. I was taught the three point landing procedure first. Wheeler landings were only taught as part of cross-wind landing procedure. I must say that wheeler landings on Manchester Barton's rough grass runways were terrifying enough after a couple of dozen hours doing three pointers. I should not have like to learn wheeler landings first.
