So let's build the whole system with -O0 and we can throw away most of
compilers and half of debuggers, which are all needlessly complex and prone to
faults due to -O2.  Do we want to build simple system or good system?

I am aware of it, I have spent a lot of time making tools prelink compatible.
But even compilers have very complex parts for negligible gains.

I really have not yet seen any valid one.

I would not say it is lost in noise but let's say it is not big.
