Say I have been using an RPM of a browser (firefox, chrome, I don't care), and I want to switch to flatpak.
It would be great if when installing the flatpak, it knows where that browser's config comes from and offers to copy my existing configuration into the new, sandboxed, location, so that I'm not starting over from scratch.
(Additionally, it would be nice to have an option for a symlink to help those of us who know the old location.)
