I'm all about this but what about third party static sites like everything on Github Pages? We're using Github to host http://kili.io which has all of our marketing material but there's no way to upload a certificate there. I'd rather not move off of Github Pages for the main site because it's easy to just push changes, it's fast, it makes it easy to tie into the rest of our open code (https://github.com/kili), and it's free.
Nice organization and cause, looks really interesting. Not being snarky at all but asking - you provide hosting but aren't able / won't host your marketing site on your own servers? Even if you don't have your own infrastructure, even grabbing a VPS from digital ocean or linode and throwing up a cert there could solve your problem.
