Does http3 have a problem with amplification on the first answer packet?

I'm not sure spoofing is something transport protocols have to solve though. Authenticated bgp and source filtering is the layer for it and we needed it for decades already.

If I remember the amplification is about 3x, you need acks for the server to send more than that.
