nit, delete as LRO seems to work as the response is

    | ArmDeletedResponse
    | ArmDeleteAcceptedLroResponse
    | ArmDeletedNoContentResponse
    | ErrorResponse;

[cataggar]

@weidongxu-microsoft , I'm not sure what you mean.

[cataggar]

As this is a nit, I'm going to merge the PR without this change, but I would still like to know in case it can improve our spec.

[weidongxu-microsoft]

LGTM. Please wait for Mark's feedback as well. I am not the expert on templates on ARM.

[cataggar]

I really need to get #32946 merged, so I am unable to wait more.
