It looks like that should be happening soonish if I read the Github issues correctly.
https://github.com/ietf-wg-acme/acme/pull/124 is "Enable the server to specify requirements for issuance" which seems to include wildcard cert support, but was only merged into master about 5 weeks ago. I presume further discussion is ongoing.
Personally I'm glad that they're taking the time to get this right. They could have probably supported wildcard certs a while ago, but it would have been through some mangled and limited method. The method they're now looking at seems to be much more future proof.
Of course, I may be completely wrong about this, but the above is what I gather from following the issues.
