Let me describe the context of the application of tarpitting so that it
becomes clear. I am looking to tarpit only certain connections based on
certain criteria (otherwise, of course, why would I even bother to run and
use nginx to tarpit, right?).
I intend to use this to tarpit persistent blog spam. I have captchas that
work - but still, I'd like to be able to punish these guys - and drive them
out of even my logs.

I'm not so sure LaBrea, or HoneyPot can tarpit selectively. Or even if they
do, whether they can work in concert with an actual web server (so that they
can pass the legal connections onward, and things will still work).
In the meantime, here is your PSA:
