It is nice to get it all in one component, even without a valve.

I agree... but I wonder if it could be drilled out? I can't think of any reason for the hole to be that small - there are no internal components, and is presumably turned from one piece of brass.
Judging from one view on the Amazon page
, the hole is only that small at the very tip, so it would be easy to drill. It's like an orifice plate rather than an extensive restriction, so I wonder if it is intended to limit flow and pressure for someone using it without adjusting the regulator down to an appropriate level? Perhaps that's the feature which they claim is patented, since there's nothing patentable about a 3/4”-11 NH hose thread to male quick-connect adapter.
