Although Haiku has a good package management, and knowing the [common insert untrusted binary download warning here] that we know about, would be interesting to have some kind of bundled app that include the required dependencies for big apps?
Something like AppImage on Linux (or FlatPak/Snappy, but those require a server, i mean ones for standalone apps), or just port the AppImage tools to make Haiku AppImages.
Note: not remove/replace packages, but for an alternative way to have apps on the system
Ps: The world is quite small, and seems like Alexander Larsson is the author of a precursor of FlatPak and also the same author for the Broadway backend i talked about in the GTK3 topic.
