[Dragonball Z] What if it turned out that humans were able to do the kaioken without any (or much fewer) consequences?

Goku's use of the kaioken demonstrates that it takes a massive toll on the user, and is often used as the reason no one else used it, at least until Goku did with SSJBKK. But what if by some quirk humans were just naturally more able to perform the kaioken without the same level physical abuse? How would the various sagas have played out differently?

Probably shit stomp Radditz and Nappa but that's about it. After that power levels rise so exponentially humans just can't keep up. Saiyans needed numerous Zenkai boosts and forms while Namekian had to merge to rival the power of a super Saiyan.
