isn't there a big problem of over stressing the airframe as you simply can't feel / nor have any consequence to extreme handling?
This is no problem (compared to everything else that needs to be sorted) because fly-by-wire systems can be made to observe any limits your heart desires. And, if by some amazing chance you are not using FBW, then you can have a g meter on the ground as easily as heading or airspeed or height or whatever.
