The thing is, if you want to deliver something that is suitable for
distributions (which the current QtWebEngine is NOT!), you will need to fork
Chromium, because upstream does not care about the issues.
Distributions such as Debian support many architectures. The Debian
maintainers I've been in contact with over IRC were really unhappy to learn
that QtWebEngine depends on V8. (They had not realized the implications of
and browser code hardcoded to use only that engine (they removed the JS
engine abstraction layer from WebKit and hardcoded V8 all over the place!)
is horrible for portability. In Fedora, our primary architectures happen to
be the ones V8 is targeting, but we do have secondary architectures on which
we do not want to desupport large parts of Qt (such as Qt Assistant) and
The bundling thing also really MUST be resolved. (At least the bundling of
the many system libraries by Chromium. If you communicate that you have to
bundle Chromium because you have to fork it to remove all the other bundled
libraries, that will likely be a convincing enough argument to justify
bundling Chromium.) It is just not practical to ship a second copy of dozens
of system libraries, all built as part of QtWebEngine. This is a nightmare
in terms of disk space, RAM use, potential for symbol conflicts and delivery
of security updates.
We distributions also very much want the web browser to use our shared
multimedia stack, i.e. GStreamer.
Then, the advantages of going with Chromium quickly start to vanish. IMHO,
QtWebEngine is the one that should be deprecated.
