Qtwebkit (qt4 era package) is dead upstream, and has hundreds of known CVEs. Also, it requires qt-location, which does not build against current proj versions. It's time to remove qtwebkit from the distribution. See also [https://bugzilla.redhat.com/show_bug.cgi?id=1711519 #1711519]

Qtwebkit is one of the few packages which still needs python2 to build.

Qtwebkit removal

Summary

Qtwebkit (qt4 era package) is dead upstream, and has hundreds of known CVEs, many of them being remote code execution bugs. It's time to remove qtwebkit from the distribution. See also #1711519 which has been open without action for years.

Qtwebkit is one of the few packages which still needs python2 to build.

User Experience

Some old applications will disappear.

Dependencies

See above.

Contingency Plan

None.

Release Notes

Fedora 37 will drop the unmaintained and insecure qtwebkit package.
