I guess it depends on the filesystem implementation. For instance, XFS returns an error if a weird file is detected [1], whereas bcachefs ignores it (which is considered a bug, but not fixed yet) [2].
If a filesyste, returns an invalid mode that's a file system bug and needs to be fixed there. Warning in a consumer is perfectly fine. But the right action in that case is indeed not to grant the access.
