In most responsive designs, there are images whose resolution depends on both the viewport width and the devicePixelRatio. Your approach technically allows handling both, by combining max-width and max-resolution MQs, but if you have 6 widths and 4 dprs, you have to write 24 separate MQs, for every combination. This is the same problem srcset's "w" unit had; see xanthir.com/b4Su0 for a clear explanation, and compare the extreme verbosity (and incomprehensibility) of the srcset example there, with the much simpler equivalent src-1.
