And you still can't can self certify.
Skill issue, you've always been able to self certify. You just have to know where to drop the self signed cert or the parent/root cert you use to sign stuff.
If you're running windows, it's trivial to make a self signed cert trusted. There's an entire certificate store you can access that makes it easy enough you can double click it and install it and be on your way. Haven't had a reason to figure it out on Linux, but I expect it won't be super difficult.
