Are there any plans to convert this work over from json to UCL which Free=
BSD uses for things like pkg? It is my understanding that UCL can parse js=
on anyway, and is the preferred format for FreeBSD from what I can tell?

Yes, I do plan to migrate from JSON to UCL, and there's an open ticket
in GitHub about it:
https://github.com/mheily/relaunchd/issues/1
However, in terms of priority, it's not at the top of my list. Before
rewriting the parser to use UCL, I'd like to finish implementing the
missing functionality documented in the README:
* unloading jobs via launchctl
* cron functionality - StartInterval, StartCalendarInterval
* file and directory watches - WatchPaths, QueueDirectories
* restarting jobs if they crash - TimeOut, ExitTimeout,
KeepAliveTimeout, ThrottleInterval
* resource limits - SoftResourceLimits, HardResourceLimits
* miscellaneous - LaunchOnlyOnce, inetdCompatibility, EnableGlobbing,
RunAtLoad, Umask
If anyone wants to help implement these missing pieces, or if you
enjoy rewriting parsers and want to play around with UCL, let me know.
