This is a good thing - you might swap out one image reference and allow
for a new graphic to be embedded.
You are not really looking for "embedded" images, you just want one data
stream with all the data "local".

If you looked at this like HTML you would be asking for HTML 4.0 to have
a facility to include binary code within a document embedded. Which
would bloat the file size among other things.  Why not simply wrap your
SVG and related images into say a ZIP file or a JAR file?  Then perhaps
include a built in gz reader that might unwrap your zip on the fly to
"read" it.   Or, alternatively, you could create your own "super SVG"
spec in XML that allows you to embed both SVG and your binary code at
once.  Perhaps something called SVG-binary.  That's the cool nature of
XML is that you can interleave languages now...
