Why? Why not pad requests to guarantee attenuation vector until
authenticity of packets can be verified?

MinimaLT does this. I think all UDP based and initial TCP should do
it, doing it for existing protocols may not be possible, but why not
for new?

I proposed similar method for proxy-trace (bidir tracerouting) -
