I'm of the "use and abuse what you can when you can". When the status quo changes, adapt or find the next thing. If all FF value comes to an end then move onto the next thing.
There will always be something new and shiny to do. For all we know some smooth talker will convince rich investors that private jet point redemption are the way of the future and start a business that we get to abuse.
At this point, QFF status quo hasn't really changed. What it's been the last couple of years is still what it'll be. There'll be less heat when the senate asks them about rewards program and lack of availability but as of right now it's not really changed.
If you find value in QFF points, continue doing what you're doing. If you find it useless, continue trying to burn the rest and move to different programs.
I don't think today's announcements should be changing anyone's status quo on QFF.
