Would it be possible for the FUSE file system to implement this
inheritance by a dumb-copy of the ACL-related xattrs of the parent?

This would solve your problem. But in addition to that, it also seems to
me that even if a file system uses default_permissions for ACL handling,
it may want implement a different policy for permission inheritance...
