XML encoding *is* significantly slower, especially because gzipping isn't just an option but a must if you take a look at the increase of size in case of XML.
The sole reason for compressing is because the network connection is too slow. Does that hold here? It would be nice if the server allowed for both compressed and uncompressed transparently. Also gzipping is rather slowish :)
Concerning immutability, I seriously fail to see any advantage of immutable data objects because the immutability can be circumvented anyway. In my world immutability deals with that you cannot CHANGE a current object, but you can create a new object based on an old one. It gives a different mindset.
