Or, at some point the experiemental IEs should be standardised through 
IANA / IE-doctors.

The problem is that once you have your own PEN, there's no incentive to 
transition your private IEs into standard IEs.

A PEN/IE registry could be a good way for IE-doctors to discover useful 
/ duplicate IEs, and create standard versions for general consumption.
