[Bug /Question/Request?] config.loglevel

To keep it simple:

I'm trying to log what routes are called but **not the result**, and changing between :
```
* - INTERNAL use it for logging calls and other internal stuff
* - DEBUG recommended to use it for debugging applications
* - NOTE development verbose information (default)
* - INFO minor information
* - LOG significant messages
```
does not seem to do much. Am I missing something ?
If I change the `loglevel` to `WARNING` nothing shows up (maybe errors etc) but not the routes being generated for instance.

Is that the expected behavior ?

(running the latest version of everything)

The issue names only the loglevel configuration and route generation, with no files or tests. Start by reproducing the reported behavior with each listed log level and inspect how route calls are logged. Done means documenting or correcting whether routes should appear without their results.
