Currently, the email verification endpoint assumes that if you only provide the email address, you are not in a PKCE flow, which means the verification ends with a redirect, or no content. However, most of the supporting libraries expect that verification ends with a PKCE code exchange. Adding an optional PKCE challenge to the email verification endpoint allows the client perform the PKCE code exchange even if they only have an email.
