I can't remember where I read this (somewhere on the internet) so it may or may not be true. But, the article had talked about how Judo had changed from it's emphasis when it started till now. It talked about how many of the Kodokan students would get into fights to test it and also if they couldn't knock out there opponent with a "judo chop" right off it meant that they had a lot more work to do.
Also, if you look at the old WWII combatives it was based on the "old" kodokan methods and included the strikes, throws from the kata.
