Specifically I'm talking about this question, where the accepted answer is fantastic. Sources, graphs, full of useful information, well-written and easily understandable.
Unfortunately it's not complete. It's not like radiotrophic fungi are common knowledge, they're kind of a corner case with lots of fairly recent work. However the question is trying to get at the existence or nonexistence of exactly that corner case.
So my question is this: What should I do with this?
- Give a separate answer?
- Edit the answer as is?
- Should I downvote the answer for being not-quite-correct? (I really don't want to, it's a very good answer)
If it was a nearly-complete question that was correct but perhaps left out something I thought should be maybe mentioned, I'd comment. If it was completely wrong, I'd downvote and answer myself. I'm a bit stuck because the answer is missing only one detail, but the detail is (imo) crucial.
What's the polite/correct thing to do?
(I've given a separate answer, but mostly by reflex. I don't necessarily favor that approach)
