Chris Bergin has the story. As he notes, the company is clearing out its inventory of previous-block boosters.
[Update a while later]
Hearing that they’re targeting 13:30 on February 6th for the launch attempt. That’s cutting it close to when I have to fly up to DC.
While SES-16’s weight compared to other SES satellites would likely allow SpaceX to recover the booster on the Of Course I Still Love You drone ship, SpaceX will likely use the expendable nature of this booster to test landing and atmospheric entry techniques while ditching the booster in the Atlantic in an effort to clear out the Block 3 Falcon 9 stock in favor of the currently operational Block 4s and soon-to-be-operational Block 5s.
Maybe they should do this over a dump.
