But that isn't true.  It sometimes takes extra work to debug because of
optimization, but it's not some kind of impossible burden.  Where the
best tradeoff lies is very much an individual thing.

Convince them to do what?  They give you a bazillion knobs which you can
use to tune the tradeoffs made to your liking.  You can argue about the
defaults, but -O2 _isn't the default_, and it's not even the default
with -O.  What would you have them change?
