Another reason to stick with XML is, that if you switch to JSON, you modify the "maintenance contract". XML is more typed than JSON is, in the sense that it works more naturally with typed languages (i.e. NOT javascript).

If you change to JSON, some future maintainer of the code base might introduce a JSON array at some point which has mixed type content (e.g. [ "Hello", 42, false ]), which will present a problem to any code written in a typed language.

Yes, you could do that as well in XML but it requires extra effort, while in JSON it can just slip in.

And while it does not seem like a big deal at first glance, it actually is as it forces the code in the typed language to stick with a JSON tree instead of deserializing to a native type.
