Distributors entering Flatpakland

Using Flatpak for businesses is easy, that is an upside, especially if you ship some kind of Electron app. Corporate does not understand that you ship the sources alongside the basic Electron binary.

And – as a user – there are some applications (proprietary) I'd really love to lock into a very special sandbox, eg. stuff like Steam. Yes, I want to play whatever game I chose, but no, I don't want those to give access to my system.

So in summery: for everyday applications I want my distribution's (Debian's) binaries or a custom rebuild. But for proprietary stuff I do want to lock them into a tightly controlled sandbox, that Flatpak can provide.
