Why are they for sale? and if the user is replacing them, what are they replacing them with?

My understanding is the, albeit less expensive, ZWO IMX455 model uses a consumer grade sensor.

My understanding is that the only difference between the consumer and industrial grade is the operating temperature range and vibration resilience. Everything comes off the same production line, then is graded based on some kind of metric that determines whether it can be classed as consumer or industrial grade.
I daresay that the industrial/consumer grade classification is more marketing hype than anything, and to realise the benefits that using an industrial grade sensor would have, need to be supported by industrial grade design and other components.
