Hi Éric,

Thank You for the review! Please see inline.

    >   indicate that this specification updates RFC XXXX.]"

Originally we assumed that trickle-ice was going to be published before ice-pac. The reason trickle-ice has been on hold in the RFC editor queue is because it is part of the Cluster 238 collection of drafts, which all are intended to be published at the same time.

Having said that, we think it is more clear to fix both RFC 8445 and trickle-ice in the same place (this draft). Much of the content is describing the problems, and making the trickle update in trickle-ice would mean that we would have to copy/paste most of the text there.

English is not my native language, so I hope Justin can comment on this.
    
Regards,

Christer
