For a lot of calibre user is this usage quite normal as most E-Reader devices in the past (and today also) had always a limitation for max resolution. Wrong picture sizes can be in best case a point of not opening an ebook, in worse case it crash the reader and only a hard reset will start the reader again.
This is why this is driven by device. In addition, if a device don't need to rescale pictures it will handle ebooks much faster.
