I think the point of this material is to ENCOURAGE random assignment
rather than sequential to improve privacy- so keep it at that. Let
implementers worry about how efficient an algorithm is?

There are a number of operational and security/privacy considerations
that depend on the actual algorithm that you employ.

I'm not sure what you mean by "random". IID=random() everytime an
address has to be leased? -- or do you really mean "unpredictable"?.

At the end of the day, what you want is to specify desired properties.

Besides, assignment of sequential addresses should be banned. They have
always been a bad idea (see
<https://tools.ietf.org/html/draft-gont-predictable-protocol-ids>) and
they shouldn't even be considered an option.
