The only difference with FEP is that if you slam the sidestick to one side then you won't crash the aircraft.
The corollory to that is if you haven't got enough control authority to crash the aircraft you probably haven't enough authority to recover it from a major upset either.
Your "padding" of the FEP limits may be the difference between recovery and disintegration and under current control laws this part of the envelope can't be entered. Despite stress predictions, ultimate load tests, failure path analysis and all the other good stuff, airframes do not necessarily break apart when overstressed as has been proven many times.
When it all goes pear shaped you want to be able to control the aircraft by whatever means necessary, not negotiate with it.
