In my opinion, supporting anything before R2000 is a complete waste of time...that's the oldest you ever see in a work environment.
Well, R13-R15 support is what we've got for now. It was easier to implement and it works, and we won't throw it away. From now on, we should focus on R2004 and R2007 header parsing. If it works, then we'll be R13-R2007 (more or less buggy) capable, since entity/object parsing is already written (but not fully tested) for all documented versions.
