That's how Werdum got into MMA. He was choked out with a triangle when he tried to pick a fight with his ex-girlfriends boyfriend.
To answer the OP, I'd rather have it than not. IMO it does have its place in self defense but as others have pointed out, it is very outdated as far as self defense goes. No one walks around with suits of armor and the only available target is a joint or throat.
