Those tend to be just pre-configured to maximize such gaming performance, often at the cost of security, compatibility and stability. Most of those stuff could be adapted to other distros, and tend to be actually. If a change or piece of software made such important benefit to playing games, without any huge drawbacks, be sure it will surely be soon integrated in other distributions.
To be fair, I’m in the same situation. Fedora, Libsteam_api.so and more dependencies and all. Do want to share it out, even if I didn’t work for me. No idea if it is a case of “Source only” or if the devs don’t really know what they are doing and forgot to remove non-free dependencies like the Steam Integration.
