To help answer why ARIN should handle in-addr.arpa delegations;

Scenario;

Assuming ARIN is allocated xxx.0.0.0/8 by IANA they handle
the in-addr.arpa zone for this. This also brings responsibilities 
with it.

If ARIN gives xxx.1.0.0/16 to ISP GOOD then they could
be responsible for that /16.

Suppose ARIN registers 

xxx.2.0.0/17 to ISP ABLE  and
xxx.2.128.0/17 to ISP CAN.

Who handles the reverse delegations for xxx.2.0.0/16?

I would suggest the same people that handle xxx.0.0.0/8, 
in this scenario ARIN.
