That's a fair opinion to hold, but the fact of the matter is that a SHOULD
for DHCPv6 conflicts with RFC 7934 and RFC 7844.

We shouldn't publish a host requirements document that contradicts the host
address assignment BCP and that cites RFC7844 while contradicting that
document's recommendation to use stateless in preference to stateful.
