I think I don't agree simply because the irreversibility of murder is so central to it.
For example, if I attack you and injure you so severely that you are hospitalized and in traction for months, but eventually fully recover -- that is a serious crime but it is distinct and less serious than murder.
Turning you off for the same duration would be more like that but without the suffering and potential for lasting physical damage, so I would think that it would be even less serious.
I think we actually do have something of a comparison we can draw here. It'd be like kidnapping a person and inducing a coma through drugs. With the extra wrinkle that the person in question doesn't age, and so isn't deprived of some of their lifespan. Still a very serious crime.
Plus everybody else does age, so the damage done isn't just depriving them of freedom, it's depriving them after they wake up of the life they knew. Some functional equivalent of the death of personality, to the degree personality is context-dependent (which it is).
Now me: I'd love to get into a safe stasis pod and come out 200 years from now. I'd take that deal today.
But for most people this would be a grievous injury.
