I don't see any benefit to programmatically-generated reverse DNS.  I
stopped setting it up a long time ago now.  Really, reverse DNS these

- mail servers (where it shows a modicum of control and clue)
- infrastructure/router IPs (so mtr/traceroute can show useful info)

I would say the absence of reverse DNS tells useful info to receiving MTAs - to preferably not accept.
