This is BS. Sure, people have thought about the defaults, but it doesn't
mean that the packager doesn't know what he's doing either. Some
software, particularly numerical computation stuff, is built for being
optimized properly. There are some extreme cases where using -O2 instead
of -O3 simply makes a piece of software useless (take Blitz++ for example).
Using -O3 in specific cases isn't that big of a deal. In any case, if
there's something the packager hasn't thought about, he'll be quickly
reminded by way of the Bugzilla.
