While it's not a great fit for our "core" Q&A experience, I've found over time that for the process of running the community, we often do ugly things with Q&A engine in order to get a desired outcome. As such, I feel like site metas and Teams could use a polls feature.
Either when trying to get an opinion from the community (which may involve a pair of Yay/Nay) questions, or trying to run an election for ROs, the 'only' real way is to post multiple answers, and base it off the vote. In some cases we just go entirely off the network and end up using third-party tools. There's a few interesting stories of processes that seem really heavy when trying to run things 'outside' the usual election cycle, or aren't a great fit for Q&A.
Having some kind of lightweight system of polls - possibly as a higher reputation privilege, as something you could embed in a question on meta or inside teams might be useful for the process of running a site. It's an unusual fit for Q&A as a whole, but might be a useful internal governance tool and ease processes where we need to run things or get opinions on direction for a site, or gauging sentiment a little more directly.
This certainly doesn't negate discussion and answers. It does give a more directed way to get an idea of sentiment on a topic.
