From FIRST:
"Caution advised regarding the ½” drill motors.
You may not replace the blue wires, however, you may shorten them such that there is a minimum of 1.5 inches still attached to the motor and solder heavier gauge wire to their cut ends. Do not attempt to unsolder the blue wires from the brush housings.The plastic brush support housing will distort if exposed to soldering temperatures and the alignment of the brushes will be affected, which can permanently degrade motor performance."

This is a caution to benefit you so that teams do not accidentally destroy their motors or cause them to not perform as well. You can solder or crimp or do anything else to the blue wires as long as those blue wires are at least 1.5 inches long and still attached to the motor (having never been tampered with). This update is for our benefit!!!!
