Glen, I think that raises another important point. If the noise reduction isn’t too intrusive, then it might go largely unnoticed in widefield. I’ve seen reports on CN that it can give rise to green stars, but I don’t own one myself.

Another good point regarding thermal behaviour too. The shrinking of many camera models could result in worse than expected performance, if one model is unwittingly assumed to perform similar to another with the same sensor.

A good example of this is the Canon 200D - potentially the same sensor as its more pricey brethren, such as the 80D, which comes in a larger case, so may be more tolerant to long exposures. Then let’s introduce the 1500D, again (possibly) the same sensor, but being cheaper it has a more lowly Digic 4+. How much does this affect the image quality for astrophotography? It’d be interesting to compare dark frames from such models under the same conditions.
