I don't think that was explicitly mentioned as part of the rumor... only people who were afraid that it would be the next thing to go or that the change would impact their own PFL status. Understandable for people who are sat with 2k+ XP in the bank.

I personally don't see the business sense behind giving XP an expiry date, because it encourages you to only fly as much as you need and not above, so I'm hoping the rumor is false, but let's see.
