A user asked for optional gtk3 support in www-client/chromium:
<https://bugs.gentoo.org/show_bug.cgi?id=559378>

However, reading e.g.
<https://wiki.gentoo.org/wiki/Project:GNOME/Gnome_Team_Ebuild_Policies#gtk3>
says this:

> having USE=gtk3 to enable gtk+-3 instead of gtk+-2 support is

What are your recommendations for the best course of action?

For stability and maintainability, I'd prefer www-client/chromium to use
the upstream defaults (gtk+-2 AFAIK) since it's most common, tested, and
supported configuration. If/when upstream moves to gtk+-3, we'd just follow.

I also understand we have users who are eager to run various
configurations, and expect Gentoo to be flexible and allow that. Would
masking a gtk3 USE flag for www-client/chromium be acceptable? Are there
any other solutions that might work?
