How do you think about to discuss concrete generated code any further?

Would it make sense to clarify assembler output with optimisation switched off?

Do you eventually care for code from non-optimising compilers?

I am curious when such a software design aspect can become more relevant.
Would it be nice to get rid of three questionable string terminators (null bytes)
for example?
