Bruce,
I am not sure what “printing depth limits” you mean, if not the -D flag.
If that flag’s value is not honored, we should probably fix it. If you mean something else, can you elaborate a little bit more?

Is this done via pointers? And do you expose them as such? If so, the —ptr-depth would be the flag to use

No, but it would be interesting to have a way to set default arguments to commands - We don’t have that feature yet though
