For ex. "gcc -no-atexit ..." will avoid any post-run object destructions.
This feature is very useful: if I have very performance critical application and
all my objects are simple and do not *really* require destructions I may opt for
this. Benefit: will be less extra stuff inserted by compiler and program will
run faster with better optimizations.
And often people do not destroy objects anyways.

If your objects are simple and do not need destruction, just don't
define destructors.

Disagree, it may only be determined after the optimization that destructor is
actuall empty.

Groumph.
It was said that the objects are simple and do not need destructor.
So what is the point of writing them in the first place?
