For normal use there is no advantage, but at the time of processing the data is much more comfortable indexes and to use a Vin.min for example and not having to parse all the text.
It is not something that contributes anything, and with a function it would not be complicated to create the json, but I understand that the use would be minor. I will try to do it in my server part, since I am interested in some data of the diagnosis gcode.
The rr_reply has helped me a lot 😉
Sorry for my bad english!
