Yea, and I'm a Santa Claus. When its stated what is criterion for getting Zenkai? When its said how much do you have to be beaten up to recieve one. Its only said that you need near death experience and Goku certainly got one, since if there weren't for Piccolo, he would die.

Zenkai's are always used for plot. Goku after his fight against Piccolo at the end of dragonball, got same wound Vegeta got when Krillin blasted him, and his power didn't increase at all.
