I agree with this but I would say the prefix is the only thing you should focus on.
It’s important that ISPs don’t regularly rotate your PD and it’s part of the rfc recommendations that they don’t. And the remainder of the prefix is your vlan space that is as important for VLAN routing as always.

This seems counter to Concept 6 in the OP.
Do you mean that ISPs don’t regularly rotate your PD in practice? I’d actually prefer that they did to maintain a semblance of privacy.
