Heh heh. That's part of why we wrote RFC7421. Architecturally, A=1 and prefix length =N is perfectly fine, if and only if all SLAAC-capable nodes on the link know how to generate an IID of length 128-N. In the real world this only works for N=64 today. afaik, there is no way to negotiate a different value. IMHO it would have to be pre-configured in every node on the link, but architecturally Juliusz is correct.
