I've considered doing this for cross-platform iOS/Android, but the problem there is that by sharing a functional core between platforms you're forfeiting a number of optimizations on iOS (and potentially Android, but everybody brings their own everything there anyway so it's kind of moot).
Point in case, for cross platform networking you're probably pulling in something based on cURL, which is quite functional but as far as I'm aware lacks the optimizations and perks of the iOS networking stack gets you like batching network calls and firing them when the cell antenna is already active to save power, as well as things like transparently multiplexing available connections (e.g. cell and wifi) among other things.
Of course these tradeoffs might make sense sometimes, but I think it's important to recognize that a cross-platform core isn't pure upside.
