Fallback and SVG support for NuxtImg?

[IvanhoeGrozni]

Is it possible to add fallback support for NuxtImg, so if AVIF doesn't work in a browser, WEBP is displayed instead?

Also, if I set the default format in the default IPX provider config like this:

image: {
  ipx: {
    modifiers: {
      format: "avif",
    },
  },
},

then I cannot override the format for SVG images, which I want to stay SVG (if I try to set <NuxtImg format="svg" ... /> it converts it to JPG, which seems to be the default if a format string is not recognized).
