I sent their tech group a query about this and why they don't do both.  But if 
I had to guess, I imagine that it's yet another way of differentiating their 
residential and business class services. For example, since most ISPs don't 
want you running full Internet type server/services out of your house.. not 
providing matching A/PTRs would be yet another way of pushing folks toward 
business class (since non-matching for/rev would preclude solid mail server 
interoperability (unless you had an external smarthost you could utilize)).
