Getting several out of date package errors during Topgrade now, so I checked with flatpak uninstall --unused, and it threw me a lot of them:
These runtimes in installation ‘system’ are pinned and won’t be removed; see flatpak-pin(1):

All I find online is that you have to unpin those manually, one by one?! This can’t be the intended way to deal with constantly accumulating flatpak leftovers, right? Why can’t flatpak clean up after itself?
