True on both accounts.
Master Cylinder stoppers are made to reduce flexing of the vaccuum tank and secure the master cylinders to exactly location, so that under loads of hydraulic pressure it won't move around to reduce pedal feel. It does not add to the braking force required as all modern brakes are good enough to lock up all four tires on a moment's notice (if there's no ABS that is...)
It is the partial and forceful braking operation that is key to performance driving and for many cars this MCS is a beneficial addition for those who know how to use the brakes well. Having said this, it is few and far between for self-proclaimed enthusiasts who don't actually have titles in racing events... But, the benefits are real for anyone aspiring to become a proficient driver, and it does also reduce wear on the master cylinder walls internally since it will help hold that device in alignment better.
As for bending stuff in cars by adjustable braces. That's just the fault of the installer, as anything with a turn buckle acts like a jack/press, and if you are twisting that thing well beyond necessary tensions, it can totally bend stuff on the car. LOL! It's meant to hold the car in current dimensions! Not to bend it out of alignment!!!!
The adjustment is there to take any variances in older cars which may have a few millimeters stressed out of alignment or specifically brace-spot-welded uni-body which may have slight growth from heat treated body structure expansion.
