So we traded a proven, reliable, physical laws based method (wheel roll) in favor of unreliable electronics. Nice.
It's not really that reliable as it it will depend on the diameter of the wheels that can vary with pressure, wear, and and actual tyre size.
A better method may be a sensor like the one used in optical mice.
Fair, and thinking about it it doesn't account for unnecessary wheelspin
It absolutely does. Typically, all 4 wheel speed sensors are polled and averaged, so unless you're doing lots of extended 4 wheel burnouts, you're talking an incredibly small margin of additional error.
