If paypal were to create a new 
service, it would want to borrow from its reputation.  An ability to 
express some means at the domain level would provide for that 
portability.  Absent that it has to go through the whole rigmarole all 
over again.

I believe the above is off topic. However, if paypal was smart, it would
of signed its messages with a d= parameter that doesn't match any domain
currently used in their email, say d=corp.rep.paypal.com.

If they wanted to provide separate reputations for each service and be
able to take advantage of a established reputation, they'd sign twice:

d=corp.rep.paypal.com
...
d=123.rep.paypal.com


AND if they wanted ADSP, they'd sign 3 times.
