This was the response I got:
From Moz support:
Apologies about this! Unfortunately, the version of python we use does not support SNI and in order for us to upgrade to a version that does, it involves completely re-writing our crawler which can take some time. We have learned of more sites running into this issues, so it is a priority. I can't say exactly when we will have an update. Sorry for the inconvenience!

Not ideal, so I queried them about us having to pay $/month to Cloudflare to overcome a technical issue that should be supported (IMO) by Moz.
From Me:
Thanks for this: now I understand why it's not done. the only things I have to say in reply are:
-
We now have to pay $XXX/month to Cloudflare mode that we need to in order for Moz to crawl the sites. Can you please arrange to compensate us for this in some fashion? Either some more projects available to us, or perhaps a couple of months free? I really don't believe it's fair to ask us to pay more on other services in order for Moz to be able to spider our website, considering what we are doing is totally standard.
-
The non-SLI issue has been going on for months, if not years. So cannot really be a priority for Moz. I'm not the only one stunned on the forums.

From Moz support:
I'm afraid we don't offer compensation for these SNI issues, unfortunately. It's a limitation of the technology right now. Rewriting crawlers takes a significant amount of time and effort, and although it is high on our priority list I still don't have any estimated release dates of when you might see a new one. Sorry about this!
