BV 1.0 exists and is final, so your argument is invalid. The proposed
integration is simple, only for Java EE environments, and is not BV
version dependent.

Which means that we would need to talk vaguely about "some" validation, which makes me wonder how useful such spec is. As for the suggestion to specify the integration as part of EE platform spec, I'm not convinced we should define JAX-RS specific algorithms outside of JAX-RS spec. That would make things just less transparent.

I do not think it's fair that they're now trying to rush it on our end by suggesting we adopt some half-baked solution that smells more like a workaround than a reasonable spec work to me.
