One response packet for one query packet doesn't
sound like much of a PPS amplification to me.

If PPS is a victim's bottleneck, then attackers might
just as well use their primary bandwidth without any
type of reflection (disregarding fragmentation, which
can already be taken care of by "max-udp-size" today).
