I prefer to have more decisions in Makefile than configure, but this
wouldn't block the patch. What we have now is a mess anyway.

There is one difference, and an important one: qemu-ga does appear in
system-wide configuration files, while qemu-bridge-helper does not. In
this sense, qemu-ga is not a helper executable.
I have no idea how virtfs-proxy-helper would work, but I suspect that a
better design would have QEMU spawning it, just like qemu-bridge-helper.
