A compliant PDF reader/writer should enforce these restrictions on people who have the user password and not the owner password. In practice, either password is sufficient to decrypt all document contents. A person who has the owner password should be allowed to modify the document in any way. pikepdf does not enforce the restrictions in any way; it is up to application developers to enforce them as they see fit. Unencrypted PDFs implicitly have all permissions allowed. Permissions can only be changed when a PDF is saved.
