Coloring parts is now illegal?

Seriously? You yourself have highlighted the “intent” of the rules.

Nothing from the previous seasons matters one bit. The current rules are the current rules.

Except for that one really really red robot at worlds (I think it was 5013X), almost all robots will not interfere with the sensors. In fact, if they do, the sensor using team needs to reconsider how they are using the sensors. Should the blue alliance be penelized if a distance-reset from the red alliance fails because it sees the other robot? No! Then why should the same apply to the other sensors like the colour sensor?? There are hurdles you need to overcome with using any sensor. Arbitratily removing these doesn’t increase students creativtiy and problem solving skills. It makes it easier for them, and makes the sensors more worth the price (which isn’t nesscarily a bad thing if they wern’t 50-100 dollars)
