What makes Judo special that separates it from other brands of 19th century jujutsu is the randori and shiai system that allows practitioners to try their skills and techniques out on trained, suspecting, resistant opponents with force and speed without necessarily harming the participants every time. In the late 1800's, the ability to pressure-test techniques and theories caused Judo to rapidly surpass the other contemporary brands of jujutsu in popularity and effectiveness.
Xerox machines certainly have some competitive features that make them special but there are certain things that all copiers do that Xerox machines also have to be able to do in order to be called copiers. For instance, pretty much all copiers (in USA) use standard 110volt 60hz AC power and standard-sized paper and produce crisp copies so Xerox machines have to be able to do those things too.
Judo is a specialized modern form of jujutsu but it is still jujutsu. so that suggests that despite Judo's special distinctive competitive brand advantages, there are things that judo-ka have to be able to do because they are also jujutsu-ka.
What are those things that koryu jujutsu does that Judo has to be able to do (besides randori and shiai) to be called jujutsu?
- Arresting/tying techniques?
- Resuscitation techniques?
- Horseback riding (or the modern equivalent)?
- Some old jujutsu schools even had a swimming in armor component.
