I wonder if they'll have any luck convincing other LLM vendors, such as Google, Meta, xAI, Mistral, etc, to adopt this protocol. If enough other vendors adopt it, it might still see some success even if OpenAI doesn't.

Also, I wonder if you could build some kind of open source mapping layer from their protocol to OpenAI's. That way OpenAI could support the protocol even if they don't want to.
