IMO, Subject should be unstructured, period. Unfortunately, RFC 1036

1035 sections 2.2.6 and 3 (including subsections).
RFC 1036 is not a standard and this is not best practice for Usenet
software. Please do not include this in the grammar.
Now, if an RFC 2822 successor were to repudiate those requirements
spelled out in RFC 1036, that would be fine.
RFC 1036 is not a standards track document and therefore should not need
to be explicitly repudiated by another document.
