I'd lay responsibility at the feet of the Guggenheim for a different reason. (not sole responsibility btw) That reason is its infamous Art of the Motorcycle Show. Relational Aesthetics has grown partially due to being a critique of the fetishization of objects that "the Art World" is complicit in, and the role it plays in capitalism. And that Motorcycle show opened the floodgates to taking object fetishization to its logical (of late capitalism) conclusion -- exhibiting mass-produced consumer goods as art.
It is interesting how Relation Aesthetics have been incorporated in that environment and context.
