I reviewed this short draft and it's clear and ready.

I have two minor questions but nothing that holds up the draft, nor necessarily needs any changes.

The draft has a 7 day limit to remember the transport parameter. Is there a reason for this specific value or is that a rather random value?

The draft says rather late that new extensions using the QUIC bit can be negotiated without using the grease_quic_bit transport parameter. While reading the previous text though I was mostly wondering why I would want negotiate my new parameter in parallel to the grease_quic_bit transport parameter. Is that meant as a failback kind of thing? If the new extension is not support I might be able to at least grease? For me these things seems rather orthogonal. But if that is meant as a fallback, it might be good to say that explicitly.
