    Hi Eric,

    thanks for your review and your kind words!

    I'm opening github issue for most reviews right now but for your comments it's not fully clear to me how to address them, so I'm replying by email first. Please see below!

        COMMENT:
        ----------------------------------------------------------------------

        Thank you for the work put into this document. Such a document is important for
        developers / operators wanting to use the new transport.

        Please find below some non-blocking COMMENT points (but replies would be
        appreciated even if only for my own education).

        Special thanks to Matt Joras for the shepherd's write-up including the WG
        consensus and the intended status.

        I hope that this helps to improve the document,

        Regards,

        -éric

        Should there be a section about temporary address extension for IPv6 addresses
        RFC 8981 (as some OS can be very aggressive in changing to the next IPv6
        address) ? Or is it 'just' a case of NAT rebinding ? If the latter, then one
        sentence in the introduction could be useful.

        What is the recommendation for these addresses, should the application keep
        always the first address as long as it is valid ? or should it switch to a new
        one ?

    [MK] I don't think this a problem as the address is usually (at least today) not changed during an on-going connection, or? 

        ## Section 2

        "permits traversal of network middleboxes (including NAT)" could perhaps be
        refined as TCP also traverse NAT, perhaps something such as "using a new IP
        protocol would have issue with network middleboxes (Internet ossification)" ?

    [MK] I guess this should be rather s/IP protocol/transport protocol/. However, developing a new transport protocol on top of TCP doesn't make to much sense. I find the sense actually clear and straight-forward. Tending to not change anything...

        ## Section 4.4 (and some others)

        Sometimes the text is a little unclear on which part of the "application using
        QUIC" is discussed: the transport layer or the application layer in the
        "application" ? Unsure whether it is only me having this confusion though and I
        have no real suggestion on how to clarify things.

    [MK] Sorry this comment is not clear to me. Can you further explain?

        ## Section 5

        For the last paragraph, should a reference to a TAPS API/parameter be given ?
        (if it exists of course)

    [MK] I don't think so; taps doesn't consider this specifically.
