It'd be nice if we could add couple of more log statements during the compression negotiation. It would make it easier for drivers to know if they are actually even triggering the negotiation during development, and also for users to identify drivers that didn't even attempt to negotiate compression (likely due to not supporting it).
When client and server don't agree on any compressors, it'd be nice to add a log line stating that
