Okay no I understand the intent better...

How about the following situation:

I have 256 machines and 1 router, that's 257 addresses required. Under
the new wording I can't then have a /23 because I have a requirement
for 253 more addresses to make it up...

(I admit its unlikely but a potential situation that needs to be resolved)

There is also a potential issue where you have a requirement to subnet
multiple locations where you are using a number less than the full
number of addresses (eg 33 sites with /29 but only 5 address being
used at each site to round up to a /23 you need more that 248
addresses...)

"Further assignments under section 6.10 will not be permitted for an
End User until all existing assignments have reached 80% utilisation"
