Perhaps it's not necessary. Are holders of IPs going to seek to transfer
longer prefixes than /24; knowing full and well, many providers are
going to filter/discard any announcements for /25 and longer prefixes?
I would suggest transfer makers and recipients give a warning
"Transferred IP address blocks may have reduced routability."
In addition, the status of a 8.3 transferred block should be indicated in WHOIS
as Transferred; and WHOIS should clearly show what the original block was.
To indicate very clearly; if you transfer out a /24 out of a block from which
only /22s were allocated; your prefix might not be propagated, because
your prefix is longer than the minimum allocation for that block.
