So what would be the solution ?

IMHO yes, having to full backup then reformat then full restore is
impractical for big FSes. Especially if they have a lot of subvols.

Also most private individuals do not have enough disks to perform a full
backup of their RAID NAS, etc.

And a FS “repair” is long and often inefficient.

I believe that we should have a repair tool that can fix a filesystem
metadata and make it clean and usable again even if this is at the cost
of losing a whole directory tree or subvols or whatever.

But it would be better to lose clearly identified things and resume with
a working FS and a list of files to be restored, rather than being
unable to repair and having to reformat everything and restore everything...

Kind regards.
