I’m dubious of faster than life travel being for reasons beyond our understanding of physics. If there were a reasonable way to do so 1 race anywhere in the galaxy could have colonized the entire galaxy or at least a substantial portion thereof in only a few million years. If it is possible it seems to suggest that life is so rare that there are very few forms of higher intelligent life in the galaxy at any given time and probably relatively few ever.

Flatpak isn’t going to have every library, cli tool, or even every GUI tool. I think in the end out of date just isn’t worth it.
