It might depend on the flag we're talking about, but filter-flags and
replace-flags is mostly used for ebuilds that don't work with supported
flags (like an ebuild that doesn't like -Os but needs -O2). There has
been a debate a couple of weeks back if ebuilds should even filter
-ffast-math as this is a flag that breaks dozens of packages, sometimes
in sneaky, hard-to-debug ways, or if the ebuild should just die if it
finds that flag.

You're free to try, but the idea is that while you have a lot of choices
when using Gentoo it is not the devs duty to stop you from making bad
choices or protect you from their effects.
