Configuration of logging is part of the API.
Conversion of objects to log info affects the API.
The API affects performance.

You need to design the API with a reference model in mind. 
Without it the API has no value. That's why you need a reference 
implementation in order to evaluate the API design.

I am concerned about performance, formatting and type safety. You 
need to:

1. define the use cases you want to cover
2. list the requirements
3. define a model

Only then does it make sense to define the API. If D is to have 
the upper hand as a system level language then the logging must 
be performant. For performant logging you might not want to do 
string-formatting at all in the engine you are monitoring.
