This is one of the reasons that FDE on an SSD is so important, even if you still have it send discard through to the device to mark blocks as unused it'll still make things much more difficult to reconstruct and decrypt deleted data later. Probably not perfect but it's one more layer of defense that will be more difficult to break.
