This is true, but this is an implementation decision you can make for 
yourself. If you want to make an identifier that has no links to any of 
your other identifiers, there's no reason why you can't choose to use an 
arbitrary IdP-issued identifier that has no connection with any others. 
You lose the identifier portability, but this is a trade-off you must 
make on your own.
