I think that's OK for a manual debugging workflow, since it's pretty
rare to want to do that under flatpak in my experience. Normally what's
most important to me is being able to easily generate a backtrace for a
previous crash using 'flatpak-coredumpctl'. Ideally
'flatpak-coredumpctl' would handle setting the right environment
variables and executing flatpak with the right permissions to make it
work. (In the future, ABRT could do something similar.)

I think we could store the debuginfo urls in repository metadata (ostree summary / oci json index) and have flatpak automatically set things up for 'flatpak run --devel'. This isn't Fedora specific - e.g. there's an eventual goal to have a debuginfo server for Flathub as well.

Filed an upstream pull-request for this (still needs some work):
