Are there any plans to add Subject Alternative Name (SAN) support for certificates generated by the managed SSL offering?
We have some wildcard certs with a fixed number (~10 for now but potentially a few more in the future) of wildcard subdomains (ie *.stuff.example.com, *.things.more.example.com and so on, but all under the same tld just at differing levels) using Let’s Encrypt SAN support. It would be nice if we could do something similar using the Fly managed SSL certificates.
I realise we could create an individual wildcard cert for each of these subdomains but for this use case using SAN has less operational complexity. Another not quite as important but still potential longer term issue if we move towards custom domain support for users is the cost aspect of that many individual wildcard certificates for each user.
