I disagree. The R3 suspension is designed for a fairly narrow statistical group of between 130 to 165 pounds give or take preferences. Most lighter riders will find it over-sprung and over dampened. Heavy riders will find the fork too soft for stable and predictable hard stops. Lowering using cheap tricks only makes these issues worse.
When I got my bike, it had been lowered the cheap way (shock block and forks slid up in the clamps). It was awful under hard stop braking, with the front tucking in and feeling very uncertain. Hard stop practice is a part of riding well, and learning. When I got the lowering junk off the bike and got it back to its proper original setup, hard stops were predictable and felt significantly better. When I changed the fork springs to suit my weight, the difference was night and day better. I can pretty much hard stop it with the rear nearly off the ground, and not feel the front end hunting from loss of trail.
The problem is, a new rider will not know is normal or what is being caused by an improperly modified rig - perhaps until it causes them an issue that results in a crash. Bottoming suspensions on a hard stop, or obstacle is not fun, and can lock up a wheel.
I personally believe that all street bikes should be set up to execute the one line of defense we have available to us that should be practiced to the point of being an automatic response - max hard stop braking. That requires the front end have the travel and maintained geometry available to support this, without getting squirrely, and also to recover immediately when the brake is released. The vast majority of crashes are from cars pulling in front of bikes, either from the side, left turns across the bikes path. You gotta have a bike that can stop NOW, and/or respond to the brake being released to execute a turn away from the crossed path. That takes stability and a fair amount of practice.
What a bike does in curves and turns is for fun, and in that case, you ride whatever is under it and live with it - lowered or not. What a bike does under maximum braking is what will save your life one day - and that should never be compromised. IMHO anyway.
