Exporting / Reporting the journal

I think that taskwarrior should be able to export journal data in some way, ideally JSON. The data is being generated in a nice form in the info command (the last table it outputs).
Ideally the output would be in JSON format, but with the workaround in #2177 it could be done with a report as well if the field is supported.
As I really like the core, but I cannot recommend command line applications to most of the people I know. So I decided to try to implement a simple UI (I know about taskwarrior-web, but it is too simple), but while scribbling some concepts I noticed there is information with I cannot retrieve via export or _get. Parsing the output that is intended for the interactive command line seems not the way to go.
As I am completely new to this project I'd like to ask for some opinions first; or maybe there is a feature I missed or a workaround for this. Please let me know. If the community thinks this feature is useful for taskwarrior I'd be willing to provide an implementation.
