The main point I'll make here is that the thread is discussing my change proposal to generate flatpaks out of Fedora content, and so the main question is whether those flatpaks are going to handle bundled dependencies in a sane way. Not about all possible flatpaks. (Note that the ability to install third party flatpaks is not listed as a benefit of my change proposal... and we already have that in F25/F26 in any case.) > Of course, one could do that in an RPM too, but then it would be berated > as a "badly constructed RPM".

While there are strong barriers in place to make sure that the RPMs that are *part* of Fedora are high quality, we don't have any barriers in place to make sure that an RPM a user installs from a third party is high quality - if a users install the Google Chrome, or Adobe Flash, or Skype, or whatever RPM it probably doesn't meet your requirements for a high-quality RPM. It's not really any different with Flatpaks, other than that we have some extra protections that aren't there with RPMs: - A flatpak can't make arbitrary modifications to your system at install time. - libraries installed in a flatpak cannot affect any other application - flatpaks are potentially sandboxed at runtime - The source repository when you install a flatpak only is used to update that flatpak and does not participate in general package resolution. So the potential damage from a bad flatpak is more limited.
