JSON format for FME Server Metric Output (REST API3)

I'd like to have an json option for the response of the metrics-api:

https://[FMEServerURL]/fmerest/v3/metrics?fmetoken=xxxxxxx

In most cases it is easier to use a json-output than a text-output.

But it isn't impementet yet. Hope to get it in some of the next versions.
