If you have some basic library that would be updated by your distribution, you have pretty much big chance that it would be part of the runtime and updated by runtime maintainers, not by the application authors. Unfortunately, this is not true. Many of the Flathub Flatpaks compile custom versions of a lot widely-used libraries. E.g., the most recently updated Flathub package of an open source project (as of writing), compiles by itself [1]: Boost 1.73, Eigen 3.3.7, OpenCV 4.3.0, exiv2 0.27.2, marble 20.04.1, lensfun 0.3.2, ImageMagick 7.0.10-13, libgphoto2 2.5.25, libusb 1.0.23, jasper 2.0.16, libksane 20.04.1, sane-backends 1.0.27, libqlr master, qtav 1.13.0, x265 3.3 Most of these are standard dependencies that are in most Linux distributions.
