We use a lot of references on talk pages. The reference pertain to discussion within a level 2 heading and thus in my opinion it would be nice to have the references appear in that section automatically.
One can add {{reflist-talk}} to have this happen manually but it would be nice to have it happen universally (or at least allow WikiProject to opt in). The references of course should only appear if some are present.
Here is an example of how the current system works https://en.wikipedia.org/wiki/Talk:Down_syndrome#Testing The next section should not have "references" listed.
