The Flatpak is already packaged and works well. It just needs to be maintained from a person that joins the Inkscape community.
This would allow further improvements like Portal support and making the app official on Flathub.
Update: One might have been found!
I’m sorry, I don’t think I can see the point you are making. Are you saying that one can get around the 3-5 people by using flatpaks, ro home directories and other mitigations?
What people?
Nonexecutable home directories I mean. /tmp too. This only makes sense as normally programs are in different areas. I will experiment with that.
