Since we can't control whether or not a 3rd part ULib or ULX addon echoes anything when loaded, our module load echo allows those who add additional modules, not written by us, to appear and show as loaded.
I've also seen where in many years past, some 'shady' add-on writers would throw additional ulx modules into their addons (that had NOTHING to do with ULX)
The echo of the loading is what allowed me to catch it on a ULX user's machine.
