FWIW, KDE is using Bugzilla for bug reporting, and Debian uses debbugs.

This is certainly non-representative, but among the projects /me personally

So, while you don't forward issues yourself, there is an intermediate
triage step which separates issues of browser applications and underlying
BTW, could you estimate how many of users which have provided
meaningful bug reports were directed to bugs.webkit.org but never made it?
