The impression I keep getting is that the existing private use subtags are in the Registry simply because they're in the ISO standards, not because anyone thought they might actually be used for something. And since the variant subtags are not related to any ISO standard, there are no private-use variant subtags that are forced to be registered.

What follows -x- is your private-use string. It can be whatever you want. 

You're asking us to register qxqxqxqx with the meaning "place-holder for private-use string". Why? Just use a string, privately.
