There are some packages that require custom work to get them to work on our platform (i.e. they may fail build or test steps). I’ll check with build engineering to see if it is something straight-forward. If it is heavily involved it will go into the queue longer term to enhance for the platform.
It will be supported later on as we have had requests for this prior, however, it is not imminent, as there are many more popular items higher up the list. I can’t provide an ETA, however anyone else that has GTK needs, should definitely raise their hand in this ticket so I can get enough demand to increase its priority.
