Dave Out of curiosity, is it linked to the (controversial) L4S work at the IETF in the TSVWG ?

It's got to be quite a lot over the past year, particularly on qualcomm and mediatek's wifi chips. I know of preseem and libreQos in middleboxes... a couple I can't talk about unless I find public info on it... https://en.wikipedia.org/wiki/FQ-CoDel Comcast rolled out DOCSIS-pie this year also. Really compelling real-world study across a million boxes here: https://arxiv.org/abs/2107.13968 Very pretty graphs starting pp14. Anyway it's looking like pie and fq_codel are winners (unlike RED). but I'd totally settle for that BCP recommending some form of aqm be available in your document at the two points so far. A deeply philosophical discussion of what constitutes a host could however ensue.

The only way we can think to avoid that is to include the DHCPv6 requirements conditionally, ie. “IF you need DHCPv6 then…” those requirements are required.
