What's up?

The change in #3374 removed tracing, which we used for all RPC debug logs.
Below is a comparison of the difference between before and after for debug logs:

We no longer get RPC level debug logs. This came up during a debugging session with users, where engineers ended up downgrading the version to get more information. We should figure out how to reintroduce RPC-level debug logs.
