The bio-bed acting up was just too silly of an issue to bring up. I mean this is starfleets flagship with the best of the best on board and M’Benga keeps working on this bio-bed, never fully fixing it? Sounds weird.
Second, they are making this whole keeping a person buffered in a transporter thing way too useful. Like the only downside seems to be that if you get a malfunction you may need to “delete” the person. I remember some episode of another series, was it Rikers clone in TNG? Where they were worried about integrity of the pattern, since it was stored so long. Did not seem to be a problem for his daughter though. Don’t like how this is so trivialized, it would solve so many problems if this could be done “professionally”.
