I like that … In fact is consistent with what I told to Mikael, that the ISP will need to have a “button” to allow the customer to decide what they want to do by default or change the prefix at a given time.

But we should not do anything to preclude privacy-enhancing methods being applied at any layer. I would argue that the BCOP text should say: a) ISPs are encouraged to support both stable (persistent) and privacy-oriented (non-persistent) prefixes as options for customers; b) stable/persistent prefixes are recommended as the default, in the absence of legal requirements to the contrary in any specific country. I’d also note that the biggest UK IPv6 deployment is a “sticky” /56 to residences; it’s hard for an ISP to guarantee a lifetime stable prefix, but they can take steps to minimise the likelihood of a change being needed.
