What would be a bold move would be to kill off a few of these legacy characters before the end of the season. If there was a damned good reason to have them sacrifice themselves for the others and make this a true final chapter for the TNG crew. Can you imagine Worf finally finding his good day to die and being with Jadzia in Sto’vo’kor? Or Riker sacrificing himself to save Deanna and Kestra? But the fans would lynch Matalas. So it ain’t happening.
