6 I disagree: The USE-enabling in ebuilds usually follows upstream.
7 IIRC there was even a policy for gentoo developers which strongly
8 suggested this.

14 I never installed apache.
15 However, especially for packages for which the choice of algorithms
16 has to be selected (USE-flags thread, jit) or of protocols/interfaces
17 (openssl or gnutls, neon or other, sqlite or mysql, openvpn[lzo],
18 qtgui[exceptions], mesa, freetype, wine), the installation of tools
19 (utils, examples, tk, perl, python) or extensions (tls-heartbeat,
20 introspection, X, readline) the defaults usually follow the
21 upstream default or recommendation unless there is a severe reason
22 not to.

26 Whether it breaks your machine/setup or not is independent of
27 whether it breaks a package.

32 Simple mathematics shows that this cannot be even closely true.
33 Anyway, this has nothing to do with our discussion.
