When an ISP's caching name servers ignore your 3600 TTL and substitute an 86400 TTL you end up disconnected for ~12 hours instead of ~30 minutes- That's unacceptable for a almost any company willing to go through the trouble of getting an ASN.There are indeed a few thorny issues with this approach; the largest issue is that all connectivity becomes DNS-dependent and raw IP addresses (from both the inside and outside) become virtually useless. Running servers behind this scheme, while doable, is difficult.
