League of Legends - Install with Flatpak

[booman]

I just read an interesting Reddit post about Installing League of Legends with Flatpak

Apparently its a simple as this:

flatpak --user remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak --user install -y --app --bundle "leagueoflegends.flatpak"
flatpak --user install flathub org.freedesktop.Platform.GL.default/i386/1.6
flatpak run org.RiotGames.leagueoflegends

Has anyone else heard of or used Flatpak?
Obviously it uses scripts written by the community, but could it replace PlayOnLinux?
