It is one of the big intended advantages, but the way it is implemented in the official client is not very flexible, and has a huge dependency list. We just added some support for Let's Encrypt to Virtualmin, and the official client proved clumsy to work with. The smaller clients that have been discussed here lately would have been simpler to integrate (and we may end up with our own Perl implementation before long, so it can be used in Webmin without adding a big stack of dependencies).
