No it didnt. Same submissions allowed in Kodokan Judo, but there were no time limits on the ground or penaltys for unskillful entry into Newaza (pulling guard/dragging to the mat).
Are you sure that the Kodokan did not recognize leglocks? Really I am asking, I am not claining to know. I have Syd Hoare's(7th Dan) book A to Z of Judo and it contains leg locks.
Are you telling me BJJ and Sambo-ist both came up with their leglocks independently?
