Rightfully relevant my behind. Talking about "aikido in a street situation" is like asking "How long is a string?" What string are you talking about? What street are you talking about?
Lather, rinse, repeat. It will never change. Never, ever, ever.
The more things stay the same, the more they change, but how does that make this irrelevant? "How long is a string?" isn't necessarily irrelevant; it's just nebulous. This might just be another example of The Thread Which Must Not Be Named, but the relevancy seems to depend on individual interests. In other words, it might not be relevant to you, but can still be perfectly relevant to others...can't it?
