Return Types (Require PHP 7+)

PHP 7 adds support for return type declarations. Similarly to argument type declarations, return type declarations specify the type of the value that will be returned from a function. The same types are available for return type declarations as are available for argument type declarations.

Personally I don't think they're needed and one may as well chuck them out to achieve greater compatibility; however if they are there it would be nicer to require PHP 7+ in the composer.json.
