Have you, or anybody else, ever done some benchmarks to see how 
"expensive" in CPU time it is to parse the exact same data in XML format 
vs JSON format?

I couldn't find FPC specific benchmarks, but did a basic Firefox v95.0.2 
browser Network tests (with caching disabled). A 54KB JSON file vs a 
121KB XML file, which represents the exact same 1000 rows of a database 
table. Interestingly (and surprising to me), Firefox managed to load the 
XML in about half the time (172ms) compared to the JSON (386ms) file. I 
did the load test multiple times, and the results were consistent.
