Don't know if this is related to these alleged upcoming SOP changes, but in early June I had a screener at SEA tell me that a new policy "soon" would be that if you leave your baggie in your bag (as I did on this occasion) the baggie gets tossed and you get booted to back of the line.

I chalked it up to the usual ........ and TSA bluster at the time, but who knows?
