The question comes down to this being a "PWM COTS servo". Knowing full well that past rules don't apply, i do take guidance on them for predicting the GDC response. For reference 2012 and 2014 both discussed
This is 100% a Q&A needed question. I suspect/predict that these are not considered PWM COTS Servos, but it's worth asking.

I respectfully disagree. It clearly is not a solenoid, so that thread is completely irrelevant. It is very much like the "DART" but that is legal with legal CIM motors. The rules in general attempt to limit output power for safety concerns. This year they seem to have gone from "4W" to warn of the roboRIO practical limit of 12.4W total for all PWM servos (blue box R29). Since the output power is safely limited by the PWM power of the roboRIO, I personally would rule it legal - obviously would need approval from my LRI.
They did ask the GDC question and got the response "In general, if a part is sold by a VENDOR as a "servo" it should be regarded a servo for the purposes of assessing rules compliance." From the VENDOR "The L12-R series of linear servos operate as a direct replacement for standard rotary servos. They use the same standard 3 wire connector, ground power and control." Legal.
