Comment (by danchr):

 I, for one, welcome our new Quartz overlords!

 One a slightly more serious note, I've had {{{-x11 +no_x11 +quartz}}} in
 my `variants.conf` for some time. The main annoyance is having to rebuild
 ports such as GTK+ from source on occasion, but that's the only issue I've
 run into. To me, ports that use X11 are mostly broken anyway; X11 on OS X
 was always a stopgap measure to me.

 I do get that this is a complicated change, and that there's a lot of
 infrastructure involved, but that shouldn't distract from the end goal.
 Here's a suggestion: Would it be possible to treat this like the Qt ports,
 and move the Quartz and X11 variants into separate ports? That way, any
 port that ''requires'' X11 can safely depend on it, and the upgrade step
 becomes much more straightforward, doesn't it?
