This is great news for organizations. I work at a large Fortune 150, and there are lots of services that require wildcard certs. We have a process to get these from our internal CA as well as a third-party - the internal CA is automated, but the third-party (for external services) can be slow and cumbersome, to the point where many departments just buy their own cert. And then a year later, they move on, forget, etc, and suddenly we have services that have expired certs and there's a scramble to fix them.
This move by Letsencrypt should hopefully make them the standard for any external service that doesn't require an EV cert.
