So basically pay protection money? We have engineered such a system that the only way to use your own stuff is to pay a tax for it and rely on centralized system, even though you don't need to be public at all?
I suggested using a domain given they already have Caddy set up and it's inexpensive to acquire a cheap domain. It's also less of a headache in my experience.
Actually, now that I've linked the docs, it seems they use smallstep internally as well haha
