Unlikely that it would be, as ACME v2 is very new (and I don’t believe it’s yet supported by the production server)
It’s really a pretty rare case where a wildcard cert would be needed. In most cases, you know what hostnames you’re going to use, and they don’t change. In those cases, no, there’s no reason to bother with a wildcard cert–just issue a cert that covers all the hostnames you want. This has been possible since the system went live two years ago, and covers the large majority of the cases for which people think they need a wildcard cert.
