I don't have commit access to this repo, so for the purposes of review I'm just some guy.

19.08 is still supported. (The reason I updated it in #5 is that it was previously on 1.6, and it was not installable with modern flatpaks!) Is there any urgency in updating to 20.08?

Github was putting you in the reviewer list for some reason. I just didn't want to overstep. I do have merge permissions.

I'm just taking some advance before it EOLs because otherwise it'll be more work at once. I calculate that over 200 applications will need to be updated close to when 19.08 (and gnome 3.36) releases, @wjt.
