Upgradeability is desirable.

As imagers and optics change, the need for different light sources (perhaps brighter) can become evident, particularly with negative, where more light = better black level.

And if one upgrades to a sensor with more pixels, the processing throughput—pipelines, CPU/GPU horsepower and storage—needs to keep up or the frames per second capability suffers.

The transport's mechanical tolerances may also need improving as more minute details become more apparent on the screen.

So it's not always as simple as swapping the sensor.  There's a domino effect.

Archives need throughput. And they need permanence (or should that be "permanence"?)

Which is why there are people investigating laser etching images on one side of a stainless steel coil, and the corresponding digital data on the other side.
