It is. But why reproject at all, if we can skip that step and serve
right in EPSG:3857?

Also, as I mentioned earlier, JPEG has "recommended" quantization
matrix that's optimized for non-scaled reallife objects. In case we
additionally make image lower on vertical scale, we either lose on
quality or on image size, as almost all of them are originally taken
in mercator-like projections.
