Parabola: Start liberating Qt5-WebEngine using the sources from PureOS?

$ apt source libqt5webengine-data libqt5webengine5 libqt5webenginecore5 libqt5webenginewidgets5
# Not Trisquel, but I've run this to get the PureOS sources for Qt5-WebEngine for liberating the same package for Parabola in [nonprism]
That's PureOS not Trisquel but still free software system (so never lounge), is this helpful to be a libre replacement of Qt5-WebEngine in Parabola that this packages is semi-nonfree in Arch? :)
