I disagree, writing an OPTIONS method seems like pretty advanced use-
case given that OPTIONS is already automatically supported by a JAX-RS
runtime. I'd prefer to leave OPTIONS out of the API for now (we can
always add it later if it turns out that lots of folks need it) since
its pretty easy to add your own OPTIONS annotation if you really need

I disagree, I think its already easy enough to create your own
annotation for a new HTTP method and there's no need to allow
@HttpMethod on methods directly.

I agree, I don't see any need for a JAX-RS user to implement TRACE,
that would be something for the container or JAX-RS runtime.
