Flatpak's dependency doesn't show up on a guix refresh --list-dependents p11-kit, as it comes through some other package somehow (I never looked how exactly). But I guess that is more "using" than needing to build against? Wondering if there are some hidden runtime cases to look out for. (Probably more relevant when thinking of changing that configure flag?)

For this bug, the fixes that I wrote did need a cleaning out of previous Flatpaks (checking how you launch Flatpak apps as our previous version put the full store path in .desktop files) as p11-kit gets started in some indirect way. I think via D-Bus and its portal, but the system p11-kit could be used instead of the fixed version. I made sure to remove previous Flatpak installs from my profile and did a restart to be sure. Noting here for completeness.
