I don't completely agree with this statement, though it has its merits. If you are using a 6s controller on 6s with marginal batteries and have "super hard" brake settings, then this statement can certainly ring true. As a matter of practice, I use a 6s rated esc on 5s max to allow some head room. I also use good batteries and only use enough brakes to slow the car - no instant lockup. I have no reliablity issues.
Any time you push a system to its limits, the margin for error gets smaller, so if you want to push the system this way, then mechanical brakes will widen the error margin. If your setup is comfortably within the limits, reliability is not typically an issue. :)
