I'm just glad we eventually got the ability to at least get some data via questId without it being in the journal or completed. (Re: GetQuestName(questId).
) I would still love any and all quest data ZOS is willing to expose through the API though if ZOSDanBatson is watching.
Including a way to map a journalQuestIndex to a questId.
I know there are things they won't expose though. Like you can't see the data for any quest stage other than the one through which you're currently progressing. Which is probably by design.
But yeah. There might be other ways to use the libs creatively. So I guess the short answer to the original question is; "possible? More or less. ideal? Not exactly."
