Codex:

Filters whether a post type is considered "viewable".

The returned filtered value must be a boolean type to ensure `is_post_type_viewable()` only returns a boolean. This strictness is by design to maintain backwards-compatibility and guard against potential type errors in PHP 8.1+. Non-boolean values (even falsey and truthy values) will result in the function returning false.
