I imagine users who rely on will be mighty upset if the ebuild did not offer those flags. By way of example, many folks here have reported their own experience over the years that a given cpu with a standard Ubuntu i586 or so install struggles to keep up with a video. The same hardware running the same software on Gentoo with sane options and USE easily manages. That's the difference between managing and not managing such things in areas where it matters. Besides, the ability to precisely control details such as mmx/sse in areas where it matters using USE is really the only thing Gentoo sells.
