One very major difference is, Thunderbolt's spec requires that this cable carry 100W of power in addition to the 40Gbps of bandwidth.

  Power over Ethernet is not too far from 100W. Maybe around 70, if I can recall correctly. So the power isn’t the biggest factor I think

    Nope. Standard PoE is 15.4 watts.
