If they are that small, you could use the 'data' url scheme.

Provided the entire file had already been downloaded.

Well, cache coherency is one and small filesize is another - I'm sure
everyone has seen a small image bloat when saved as eps, so converting
well-compressed image data into hex is not a great idea.

But for tiny images, sure, just use the data url scheme.

In addition, upcoming work on packaging would likely impact SVG in terms
of bundling up an SVG file and any other resources it uses intoa single
