Icon size information isn't actually sufficient to do both. This is the reason that srcset contains both viewport constraints and scaling factor constraints. Frequently, a 32x32 @1x icon is not the same bitmap as a 16x16@2x icon. The smaller the icon the more dramatic the effect. See http://usecases.responsiveimages.org/#device-pixel-ratio-based-selection : "completely different images may need to be used for different device-pixel-ratios" It's possible I don't fully understand how a manifest would work with the notifications API. Do you reference the json format only, or somehow think that the notification should be able to reference icons specified in a manifest?
