Historically -O and -OO have been the antithesis of optimisation, they 
change the behaviour of the program with no noticeable effect on 
performance.
If a change is to be made, why not just drop .pyo files and be done with it?

Any worthwhile optimisation needs to be done at runtime or involve much 
more than tweaking bytecode.
