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.
