I don't think anyone is saying the browser et al aren't abstractions. Think of it like this, no amount of abstraction will save you from having a network connection go away. That sort of use case adds complexity, and you can't get around it.
The browser severely limits what you're able to do with the network connection, but at the end of the day dealing with the network is a complex beast.
If you doubt, look no further than the HTML5 caching API's. The tooling around them is absolutely terrible, but even if it weren't there's an inherent complexity with that sort of thing.
