Turns out the Debian 5.10 kernel has not been built with this CONFIG_UNICODE option enabled.
Just did another upgrade today, and the new 5.14 kernel has this option. You also need to do chattr +F «dir» on each directory within the filesystem within which you want to have case folding enabled. The directory must be empty at the time this option is set or unset. The attribute setting is propagated by default to subdirectories of such a directory, but you can change this afterwards.
