Comment 4 for bug 1973033

I reviewed wpebackend-fdo 1.12.0-1 as checked into kinetic. This shouldn't be
considered a full audit but rather a quick gauge of maintainability.

wpebackend-fdo is the reference implementation of the base rendering backend design
of WPE WebKit, a port of WebKit. It is also used by WebKitGTK to implement hardware-accelerated
rendering under Wayland.

Development is active with frequent releases but it follows a release model similar
to wpewebkit (and webkitgtk) which has been historically difficult to maintain, from
the security team's point of view, due to their release model (minor version releases
with limited information related to security only issues). Since this is a relatively
small codebase and no major issues have been found during code review I am inclined to
ACK it. The lack of a test suite (and autopkgtests) though is going to make testing
difficult.

Security team ACK for promoting wpebackend-fdo to main.
