How to print full configuration, including all possible defaults

It’s as the title says.

I want to see, now that I’ve configured by backends and frontends, what the defaults are that have been set for them. Values that I didn’t provide, but the default was taken.

I tried data plane api, but the return from that is very terse and just refers to unnamed_defaults_1 with no details.

There seems to not be an option for this, which would be super-useful comparing versions, seeing if something changed that might alter behavior.
