Indeed, and it was December 2018, so over a year ago...There were about to release the FC in December, but did not finally and focussed on bugs instead. This was only very few weeks before release date. So the FC must be pretty close to ready for release, but on standby for now.
So given a delay of over a year, and seemingly more work yet applied to them - "the first half of this year's updates will be focused almost exclusively on Fleet Carriers" - Surely this implies something significant going wrong somewhere?
