I'm afraid, that's bogus.

actually read your linked article:

And from the actual RFC #8555
> Any identifier of type "dns" in a newOrder request MAY have a wildcard domain name as its value.

So, it's:

1. just wildcard '*.domain.tld', totally fine
2. if an order contains a wildcard and the base domain, it's seen as valid too,
   but definitively *not* a requirement..

2. stand in contrast to cases where a wildcard domain and a subdomain, which the
wildcard would already cover, are passed in an order - as that is bogus.

How do I know it works? Because I order wildcard certs with just the wildcard
domain since ACME/Let's Encrypt supports it ;-)
