Ok ok... there are several orgs who say they teach "sports ju jutsu" classes, such as the International Atemi JJ:

If places are teaching sports JJ, why not have it as a category? The category denotes a specific approach to teaching JJ that IMO is different to the other categories listed i.e. teaching JJ as a sport. Heck, you could even consider putting Judo in to the category of sports JJ.

IMO, a martial art is considered self defense when it contains techniques/methods to defend against:
1. Multiple attackers
2. Weapons; gun,knife, stick/bat, sword ,etc.
3. Fighting in areas other than a ring.(e.g. small space such as closet, elevator,car,-dangerous areas such as rooftops and stairwells.
4. Training focuses on self defense, not ring bouts, therefore, tapping out is not recognized as submission.
5. Sparring/randori is not limited to one's weightclass.
I'm sure this list could go on, but I think you get my point.

From reading about it on that link you gave, it sounds more like an extension or side note to their traditional ju jutsu training. Not so much a basis for an entire approach to JJ. Could be wrogn though. And I had never heard of that, which is why I asked the question.
