I don't understand. Are you suggesting adding the options as query
parameters to the URI? We obviously can't do that, because it would
change the URI. Neither can we assume that the URI will not contain
query parameters and we have them to ourselves. For example, vsphere
disk URIs, which is what I'm targetting, contain query parameters.
