bids-standard/bids-specification#1672 messes with the schema filename validation heuristic. When a the validator can't determine a datatype based on directory it attempts to validate just the filename across all datataypes for potential matches. Phenotypes are a wildcard so will always match. If you point the schema validator at a random non-bids dir, it will then suggest that all the files are misplaced phenotype files.
