Speedrunning still had plenty of engagement and devoted people in the early 2010's.
However, the routes don't really use body slam, so it likely didnt come up often. I'd be surprised is the speedrunners knew earlier than competitive.
Also worth noting, speedrunners found the manipulation mechanics around the same time as the body slam para discovery. This makes me think people were starting to tear apart the code around then (2014/2015), leading to major discoveries in the subsequent years (so neither group really was ahead of the other).
I'm sure plenty others know better than me though, Hip included.
