Reconsider Adding GameHub to Flathub

Project information: GameHub is a unified games library client

Name: GameHub
Upstream has been contacted: Yes but GameHub was rejected by Flathub. Now that Lutris is on Flathub-beta and flatpak has evolved, perhaps it would be nice to reconsider allowing Gamehub on Flathub. Relevant issue:

Did something actually change to reconsider it? AFAIK GameHub still spawns everything outside the sandbox when running in flatpak.
