There are situations where packet loss can be an issue. In the configurations I have implemented, LAN packet loss is rare. Operations are idempotent and thus can be repeated. Everybody has their preferences. Personally, I avoid having too many layers and too many intervening abstractions. In my designs, keeping it lean maximizes throughput and simplicity means that I can debug it without tearing out too many hairs. In many projects that I have worked on we spent more time debugging third party modules than the stuff that we designed and implemented.
