Short lived SSH certificates without access

Looking at the docs for short-lived certificates, it states that it’s possible to use short-lived certificates whether the server is behind access or not.

As of writing, in order to create a short-lived certificate, one needs to set up the server in access as an access application.

Are there any plans to allow the creation of short-lived certificates without having to set up the server as an access application?

In my case, the server is running the warp client and I am using warp-to-warp to access it via its virtual ip. I also created a non-public “dns name” for it using a DNS override rule in the firewall settings.
