The thing is this is not new text, it has been in RFC4291 for 11
years. c.f., 2.5.1.

And during those 11 years. Nobody implemented this rule specific to ::/3.

The point is not "specific rule for ::/3".  The point is that this is a
explicit rule for all that is *not* ::/3, with an exception(!) for ::/3.

... and still there are other RFCs that permit /126 and /127, so this
definitely needs rewording to match current reality.
