There is this feature in QUIC where their equivalent of the
ClientHello is padded to a certain significant size.  The theory there
is that you don't want your server to be used in a packet
amplification attack (ClientHello being generally smaller than the
ensuing flight from the server).  I think that perhaps there might be
a standards-based use for a feature that at least made the size of the
flights commensurate in size.
