  This is not about ipv6 or hal or dbus in particular.  My approach is
to only have the bare minimum necessary flags, and not allow *ANY NEW
AND UNNECESSARY OPTIONAL* flags.  Any additional extra "stuff" involves
additional bloat and complexity, and a chance of breakage.  If Dale had
had "-*", a *NEW OPTIONAL* use flag (e.g. hal) would not have been
implemented for X.  Some other ebuild that had hal as a hard-coded
dependancy might have pulled it, but X still wouldn't have linked to it.

  I can't fully browse the web without jpeg enebled, I get occasional
jpeg photos in emails, and the camera club I belong to insists on all
uploads being in jpeg format.  So yes, jpeg is necessary *FOR ME*.  I
accept it into USE, because it of that.  So far, I've done OK without
ipv6, or hal, or dbus, and I will continue to do without them until/
unless they offer me additional functionality that I want/need.

  I do get the occasional complaint from emerge when application A
requires that application B be emerged with a specific USE flag that I
don't have enabled.  If I want/need application A, then I will insert
the required flag for application B into /etc/package.use.  Once I see
several entries for that flag in /etc/package.use, I'll run...

USE="flag" emerge -pv --update --newuse world

...and see what else links to it.  If it doesn't look bad, I'll move the
flag into USE.
