fortunately, this change should help diversify the number of certificate authorities for people to use. In the explanation of the wilcard support they link to another post that explains it is enabled by their rollout of ACME v2.

Wildcard support is one advantage of ACME v2, but another advantage they list is "ACME v2 was designed with additional input from other CAs besides Let’s Encrypt, so it should be easier for other CAs to use" - https://letsencrypt.org/2017/06/14/acme-v2-api.html

So, in addition to this functional improvement to Lets Encrypt, the change should enable more automated CA options in the future.
