Abuse scenario:

End user registrant holds two RSA /16's and a variety of legacy
registrations including a legacy /24. He has sufficient utilization
and projected growth to justify an additional /20.

Registrant signs an RSA (not legacy RSA) for the /24 bringing it under
the jurisdiction of the NRPM.

Registrant requests additional resources.

Registrant assigned a /14 (minimum CIDR block necessary to accommodate
two /16's a /24 and a /20) and is required to return the two /16's and
/24 within 12 months.

Result: gaming the proposed policy nets the registrant 100,000 more
IPv4 addresses than he would otherwise qualify for.

Owen, I called your attention to the flaw in this text last week. I
thought I pointed it out to you last August too but I could be
mistaken. Either way, you really ought to fix it by constraining the
return to just those assignments smaller than /22.

I'd like to be able to support this proposal.
