They were obviousing expecting spammers to use the spamtrap addresses as

trying to explain why their system needs some work?  Has anyone else 
talked to them about this?


I'm not so sure that "they" (spamcop?) are not expecting spammers to
forge spamtrap addresses in the 2821.MAILFROM.  Spamcop has, in the
past, been very supportive of SPF as a way of reducing backscatter.
They have the openspf.org website linked to from their "please don't
backscatter" web page:
http://www.spamcop.net/fom-serve/cache/329.html

In the past, I have talked with spamcop folks about SPF issues.  They
may well be willing to make some changes.  It may be very possible
that they would be willing to publish "v=spf1 -all" records on the
domains that are used exclusively for spamtraps.  I think it is highly
doubtful that they will be willing to stop counting backscatter as a
listable offense.
