Plus disc wheels are not designed for this sort of use, in my career I could count two fixie-skidda coming into the shop with busted axle/hub bonding on rear disc wheels and wondering why the disc was loose despite the axle being fully tighten on the track-ends.
Discs are good for time trials and specific track events (and in HHSB builds, just for pictures tho, not real usage).
