Hey @ajs6f , I think so. My weak memory seems to tell me that the last time
I did that... shortly after, there was some work on JSON (JSON-LD? Or maybe
pure JSON) somewhere else in Jena; and when I saw that happening, I wondered if
that would perhaps be a replacement for the functionality in this ticket.
I wonder if you or @afs would be able to confirm that there isn't already
another way to get JSON responses in Jena, and that this feature is still a
nice to have feature, please? :)
