Well, just a datapoint: I do basicly 4. I have 128 bits or less of
interface id. (128 - prefixlen) bits from the least significant part
of the interface id is copied into real address (and rest is ignored).

I could as well have prefixlen < 64. Makes no difference.

However, I would really prefer that all prefixes on the link do use
the same prefixlen :-)
