The issue is trust in distributed system like this. You may put email 
address for maintainer in ARIN whois (which would be new contact most
likely) and can check if this email address is listed in RR but you're
completely at the mercy of RR maintainer to make sure the person who
updated their registry was properly authenticated based on that
email address at the time that routing registry data was entered.

To provide proper verification security for whoever checks the RR you
need something like PGP fingerprint (or just public key directly) 
corresponding  to maintainer's PGP key as part of maintainer contact
data in ARIN whois and then need PGP signature with RR data. But as
I'm sure as some would quickly notice this all looks rather like SIDR....
[oh and did I mention about those fun pk roll-over issues that all
come into play for distrbuted PKI like that ...]
