True, but no more less wasteful than using a /24 out of a larger block (if
you have one).

Ok.  If this policy is intended for allocations to organizations who don't
have PI space, I don't have any real objections to it.  I would be
somewhat more comfortable if we explicitly stated the expectation that if
you have PI space you should use it for this purpose, and only be eligible
for a micro-allocation if you're not big enough to need a PI /22.  But I
won't try to hold up the policy until the next meeting based on that
quibble.
