I am a happy firefox-user, and what I heard from other people, epiphany is simple to remove, just remove the dependency in gnome's ebuild. But since it will be overwritten after a next sync, wouldn't it be nice to have an use-flag for epiphany in gnome.ebuild, so we don't have to build both epiphany and mozilla? If it is linked to other important applications, please ignore my foolish suggestion, but I haven't heard any complains from those who deleted the dependency.
If we followed through with that, shouldn't we have a useflag disabling nautilus, file-roller, gnome-panel...You get my point. We try to ship the complete gnome distribution.
this has been brought up before (search!), gnome meta is supposed to reasonable close the gnome desktop release. In our (and upstream) opinion, epiphany is part of that. If you are unhappy with gnome meta, you shouldn't be using it (look at gnome-light). There are easy ways to circumvent this problem btw : eg. inject epiphany.
I tried searching :\ I am sorry to have wasted your time (I haven't been able to get on my imap for some time, so sorry again for the late response). I get that GNOME should be seen as a full desktop with a broad application availability, but since it is so modular I saw it also as a hacker's choice (but gtk is enough I guess). But since this have been discussed before, I leave this bug alone ;)
