Question: Reasoning for `:trace` versus `:debug` logging

Is there any specific reasoning for which log messages are on the `:debug`-level and which messages are on `:trace`?

If not: While the log output the library produces is at times useful, I would like to see all log messages log to the `:trace`-level. Endusers (that is, not developers) cannot really learn anything useful from those messages anyways.
