I will respectfully disagree.  What is the point of “should”?  Even in
the example you gave it would better as “must unless” or “shall unless”
  instead of “should unless” .  With “should” there is no reason for the
unless because there is no requirement to do otherwise in the first place.

Should leaves a loophole that can be easily exploited, i.e. “you never
said we had to do that, you just said we should, so I can technically do
whatever I want”..

Sorry, I don't have time to debate this issue in general at this moment. The PPC at NANOG 61 is just over 24 hours away.

It would be perfectly functional to say:

“The allocation size shall be consistent with the existing ARIN minimum
     allocation sizes, unless small allocations are intended to be
explicitly part
     of the experiment.”

Are you suggesting we should also change that sentence as well? If you are I need to know ASAP, like I said the PPC is just over 24 hours away and I have to finalize the presentation ASAP. I would also like to hear support from a couple others on PPML before opening that sentence also to changes, as well.

Using “should” in the statement makes it a no-op.  With “should” you can
choose not to follow what is only a suggestion. If you use “shall” or
“must” you have enforceable policy. If the policy is not enforceable it
is nothing more than a best practice statement at best.

I also respectfully disagree. However, I will discuss the issue with ARIN staff here at NANOG to understand how they interpret this issue.
