Ok, so let's leave things (untagged) as they are. I do symbols
tracking with my DEB packaging, so I should notice at least BICs (i.e.
As the situation is not optimal for these projects (they are core
components of the Ubuntu Phone) would another option be moving the
upstream location away from qt-project.org?
I am not saying that this should be the goal, I am just wondering how
