I think we should acknowledge that people often have difficulties
with the rather simple functionalities of the logging module,
not only the advanced ones.

But how is that necessary for the use case? Your LoggerAdapter-derived
class could take the "existing class" as a constructor parameter (*), then
inject the required info in its overriden process() method.
(*) either by overriding the constructor, or simply by passing the
"existing class" as an entry in the "extra" dict.
If I had trusted your doc blindly, I would have thought it necessary
to go through the "complicated scheme", while the simple scheme is
actually sufficient to add per-connection info to log messages.
