Hi,
I read the brochure, seems objective of this spec motor is to simplify (e.g. no laptops, programming) and to grow the hobby. To me it seems ideal for a Novice class.
Boosted escs made my eyes roll and confused (despite playing with rc cars for 33 years). Definitely not a way to attract new racers.
My take is this motor is to attract new racers (i.e. beginners) or retain racers who want to race at a slower speed.
Harcore racers can still race in existing classes with mod or boost.
