In that case, it would be nice to specify a more reasonable expectation than 128 bytes of storage for the icon.

128 bytes is reasonable for a URL, but squeezing icons into 128 `data:` bytes is basically futile. A recommended target of 4K or 8K is somewhat doable. (Perhaps it could be specified like `srcset`, offering a large image for computer/phone-side authenticator storage with lots of space vs.small one for space-constrained on-key storage.)
