depends........ some application looks into reverse entry.. some dont. so, reverse entry is not a must, your DNS will still work without it.
for example i have a firewall , which allows packets from abc.com only. now, the packets contain ip addresses, so the firewall will do a reverse lookup for those IP's and if it resolves to abc.com then it will allow, else it will discard it. so the person who is hosting abc.com must have a proper reverse entry, else the firewall will keep kicking his IPs out.
