Sorry, I should have said "would have moved" instead of just "moved".

The problem is that as this stuff has gotten more complex the need for an
explicit algorithm specification (or more than one, or one with a  bunch of
parameters, or whatever) has increased, in order to insure inteoperability
between different implementations processing language tags. You have
addressed this by having a more explicit description of how to match
these things than 3066 did.

Whether or not this is sufficient, and whether or not it has moved
close enough to an algorithm description for it to be an issue for a BCP
is the IESG's call. I'm merely pointing out that this is yet another
potential issue with the direction this work has gone.
