Or they don't even use the bundled rom sources and build from upstream
tarball instead.

Makes sense.

Adding some submodule (roms/prebuilt?) would also make the management
easier.

Basically the full tarball would be qemu plus submodules, and the
minimal tarball would be qemu without submodules.  You can simply use
"git archive" to create the later, which is a bit problematic today as
the tarball will include blobs without sources.
