The warnings and objections are real. Note however there was not a NOGO on
the flight, only the increment and the return flight (manifest). The med-ops
folks (CHeCs, TEPC, TVIS, etc) have a low priority on manifest, to obtain a
higher priority their equipment must be declared by them to have a higher
criticality. However when it is declared to have a higher criticality then
it must also pass a more rigorous design review (MTBF analysis, MTTR, etc).
The trade-off is that if the equipment is mission critical then it must be
shown that it will work. A casual examination of the the documentation on
NASA watch shows that the med-ops declared criticality matches the
equipment's operability.

So basically what you are saying is that they can only fly unimportant
equipment, because if it were important it wouldn't be good enough.
