> much appreciate it if you could give feedback on the vreg flags.

I think that could be fine as long as we specifically say that they can be dropped inadvertently, i.e., you can't rely on them.

That said, I believe that if we put such language, you wouldn't be able to do what you want since in theory the information could be inaccurate and at this point, having this information or no information is pretty much the same. (I would actually argue that no information is probably better!)
