I think perhaps the issue is that different people jump in with what they have been using as their definition. Sometimes to be argumentative, sometimes to clarify what they're talking about, and sometimes just to suggest a different definition for the discussion.
Heck, I don't really agree with myself about the distinction. Sometimes I'm talking about older vs. newer (even that is rather vague). Sometimes I'm talking about systems that try to remain static - keeping to the way the system was at some arbitrary point in time. Most often, I'm talking about systems that use traditional training methods that have been around for long periods of time and have become codified in the system, versus those that seem to use whatever works at the time. That last is often (by me) conflated with traditional rituals (uniforms, bowing, remnants of the language from the country of origin, etc.) - probably because I most often see them overlap.
If I can't agree with me, how am I ever going to manage to agree with you?
In all seriousness, I think part of the problem is it's a conceptual term, rather than a concrete one. And those of us who are more conceptual are comfortable with vague definition, which doesn't work well in discussion with those who are less conceptual (and "conceptual" is not a value judgment in either direction).
Personally, and this may be me being a stereotypical nit-picky student of philosophy, I would rather we try to discuss these different concepts separately then conflate them with each other.
