I said I wouldn't comment futher on the spec issue.

I know of at least one other implementation that allows any set of bits
within the link local range to be specified. (Two if you include the
current/previous Linux behaviour :-)

Changing to restrict the allowed link local addresses doesn't _enhance_
interoperability. Leaving it as it is/was doesn't harm anything.
