It's not hard. However, I'd note that IE didn't have built in support until 2011, and the first browser with native svg support was Konqueror in 2004, whereas gif and jpeg have been around for a lot longer.

Isn't SVG just XML? I'd assume you could host it that way.

It's XML based, really only uses a different schema.

What schema does XML normally use?

XML has no default schema.
