Sadly, the fact that Q400 is not prone to tailplane stall leaked out only after the accident.

For future designs, now that the issue of tailplane stall was recognized, Transport Canada mandated specific flight tests to no susceptibility to tailplane stall.

If landing flap selection is accompanied by stick force lightning or stick force irregularities, immediately retract flap to previous setting and cycle the de-ice boots several times. If practicable, land using a lower landing flap setting. This condition, which is the precursor to tailplane stall, will not occur unless the AOM icing procedure are not followed.
Somewhat confused (easily done). Are we to believe then that the aircraft is susceptible to tail plane stall if anti icing procedures are not followed?
