With #22218 we added the ability to disable decryption of files using the legacy cipher. While it allows admins to scan for files where the header is missing, we currently lack a migration path to fully drop the old code path at some point.
For master key encryption we could just re-encrypt those files in an occ command, though for setups where there is no master key we cannot do that so that would basically mean we never can drop it without the possibility to make files inaccessible. Though a migration command for master key setups might still make sense.
