urgh. massive facepalm, I completely forgot about XI 1.x.

Jasper, XGetExtensionVersion() is the XI1 request to get the extension
version. This won't lock in any version, so it's safe to call before
XIQueryVersion to get the version the server actually supports.

for now we don't actually need this new request after all.
