I slowly walked a 150ft rectangle with an iPhone and and an Edge 1030+ mostly in the open. The traces looked nothing like the actual path.

Sure. But, in the real world, cyclists aren't really doing both of these things at the same time.
Also, supporting a higher-sampling rate might make the devices more expensive or consume more power.
