I don't really think it's an issue though, if you really want portability you shouldn't rely on any software provided by the distribution unless you want to depend on that specific distro.
Flatpak runtimes are basically interchangeable base systems, it seems silly to commit to any one in particular when you can use any number in parallel.
One thing that would be interesting would be to use flatpak "runtimes" to provide a target base system for AppImages, but I don't think that level of cooperation is actually possible within the Linux community.
