My major concern is speed here. Any debug handling will make the registry 
slower; I am using adapters very heavily in my code and any slow-down of one 
lookup would be multiplied many times.

I wonder whether a different approach could be taken. The APIDOC code does 
already a registration analysis. Maybe we can use the registrations in a away 
that they simulate the adapter registry. Thus you could provide APIDOC (via 
the Web UI or Python) with a component or instance and it tells you how it 
tries to look up the adapter. Clearly that would be much slower, but okay for 
inspection.
