I'd agree if I was always in the position of starting projects from
scratch. All compiler warnings should be errors and disabling a compiler
warning has to have a valid justification during review, yes.

But try it with an existing code base. That's when you need
deterministic behaviour from your modifications with minimal disturbance
to anything else.

If you can afford the tech debt recovery time to change your compiler
warnings to errors or sift through the build output - and prove to your
QA/RA that you don't have to re-certify the product.

But you're unlikely to save any bytes using a modern compiler.

Anyway, we're off-topic so adieu.
