I used the term rockstar developer sarcastically. No I don't believe that the differences between individual developers outweigh the benefits of bargaining collectively. What I do believe is that there's a great reality distortion among developers that makes them think they're more unique than they actually are, which is a culture the tech sector has deliberately cultivated. Just like say, the image of the "nice CEO" who comes to work in a hoodie and pretends to save the world rather than doing what shareholders ask him or her to do. It's all just a stunt to obfuscate hierarchies.

And I'd stress again that I think the biggest thing to bargain for isn't necessarily wages, it's control over how these firms conduct themselves. Tech workers, almost more than anyone else, seem to have forgotten that they can be stakeholders in their firms.
