I support the policy as written.  I think Owen has a great idea, but
the timeline is a problem for changes.  It would be possible to start a
new policy to correct this one with Owen's suggested changes, but let's
fast track this one *as is*.

I'd even support this as written if it was declared to be a Board
response to an emergency.  Unless there are compelling arguments in
dissent, this should simply move forward.
