Developers came to work Monday and found over a thousand log message strings had been buried in a new header file, and any new logs required a new message id, along with a new string entry in the header file.

Developers were once again free to use plain text strings directly in logs, but the notion of "classes" (message ID) was kept. We allowed multiple text strings to be used against a single class, and any new classes went in a master header file. The "debug" message ID class was a general purpose bucket and what most coders used day to day.
