I am not speaking in favor of the status quo (a /24 minimum transfer size).

However, IMO having a /32 IPv4 minimum transfer size (no limit) would be a
bad idea.  There have been several cases where entities who are completely
ignorant of Internet routing think they have some "right" to a particular
/32, and wish to transfer it.  IMO, having *some* minimum transfer size is
a good way to prevent such efforts from being imposed on the rest of us.
 (If ARIN can point to policy saying "that simply isn't allowed", they're
in a much better position than trying to argue the particulars of each
case.)

I would have no problem reducing the minimum IPv4 transfer size, just not
all the way to /32.  So I oppose the proposal as written, but could support
a revised version.
