Support different aspect ratios for different screen sizes

In my current project I need the ability to change the aspect ratio of an image, depending on the current screen size (for responsive design). I know that you can define the aspect ratio of an image by setting an explicit width and height (if you use sizes, then it is responsive):

<NuxtImg ... fit="crop" width="750px" height="375px" sizes="480px xs:550px sm:750px" />

(Using TailwindCSS)
My problem here is, that I need different aspect ratios once I hit "md" and "2xl" screen sizes. I currently solve this by using 2 more NuxtImg components, where the 2 NuxtImgs with the wrong aspect ratio for the current screen width will be hidden via display: hidden.

My idea would be to add some kind of aspect property like aspect="2/1 md:3/5" or to integrate it into the sizes property kind of like sizes="480px/240px md:450px/750px" (which would probably be a better idea) or something like that. I don't know how that could conflict with the existing height property, but if this feature could somehow work it would be really neat.

The issue names no files or tests; start by locating NuxtImg's prop handling and responsive sizing behavior. Compare the existing width, height, and sizes behavior, then define and verify responsive aspect ratios at breakpoints while preserving compatible existing usage.
