I am getting really nervous about allowing any port other than 443.

I just did a scan of a very recent clean install of Windows and there are a
*TON* of Web servers running for apps that didn't mention they had one.

The thing is that if I am running a process on any sort of shared host, I
can pretty easily spawn a server and start applying for certs for other
domains. Not only can I get .well-known, I can have any host name I like.
