I think in the case of premium cabin passengers, the compensation is likely to be inline with what you bring to the table. If you paid coach and upgraded to BF, or were on a reward ticket, your compensation is likely to be vastly different than a customer on his 10th paid BF flight at 7K a pop.

If you fit into the latter category, I can't see CO risking the loss of a 7K/trip passenger over a PClub membership valued at a few hundred. If you fly the remaining flights on CO you said were planned, you will make Gold again anyway, so that's probably not worth squabbling over.
