It has been widely discussed since 2011 around the time of microswitch introduction that a debouncing algorithm is only required when AB is involved. Simply put, an AB FET will attempt to apply reverse voltage when it detects that the switch is in the off position, which can occur when the microswitch bounces with weapon vibration. The rapid voltage swings is what causes the overheat. Rapid application and cessation of forward current alone especially if the motor is already in motion does not represent a large increase in current draw.
Since we're throwing names around now, here is an old thread authored by the mentor of "the BTC guys" (it's only one guy by the way) - Terry Fritz aka Gandolf, who remains quite active to this day.

Here's the relevant excerpt:
"The rel problem is when an active braking MOSFET thinks the trigger is released (sub 1mS) and slams in the braking FET to stop the motor... Then 1mS later the trigger signal says "just joking!" keep the motor on... :P :P That is about a 300 amp "joke" for an active braking unit to "process" there like 100 times every second!!!!!!!!! T"
You may also want to take a look at this to understand the phenomenon.

With regards to actual first-hand experience, I recently installed a standard FET on a PTS Masada running 11.1v lipo with no ill effects after 1k rounds of mixed auto/semi fire. I anticipate the owner will provide me with an update as the season progresses.
