No, because it's a warning. The shut-up thing only blocks debugs.

I wouldn't remove it just yet. There's still plenty of output that
it's not very useful and probably should be removing. i.e. there's
plenty of networkmanager stuff going on there.

Maybe what we want to do, though, is this:
QLoggingCategory::setFilterRules(QStringLiteral("*.debug=false\ndefault.debug=true\n"));
