My concern is exactly that ... and I'll say why I think this needs thought:

RFC6828 reflects the consensus on using a larger IW, what is safe and how to use. Use of a larger initial window impacts all transports - this RFC was the first (and currently only) decision to allow more in the initial handshake period, even though that was only  EXP -  I did not see data for QUIC analysed, so I think QUIC has followed/joined that experiment, but is not itself an EXP.

If the IETF updates the decisions in RFC6298 because of safety concerns I think this impacts all protocols.
