I thought about this while answering this question. The question doesn't ask for a list, just for an explanation of whether or not it can happen. Several respondents list singular examples and one answer gives an incomplete list. Understanding the different ways very much is helpful, but does an incomplete list create more confusion because it 'looks' exhaustive? Is it better to overanswer incompletely or to not do this?
I've done some partial lists. I've always felt poorly when posting them, because they never feel like a complete answer. Here's why:
Partial lists aren't clear
A partial list leaves the impression that it may be a complete list. Upon my first look at that answer I had thought that it was meant to be a complete list or ways to gain advantage on initiative, not just Dexterity checks, and was surprised that it missed the one I included in my answer.
Partial lists invite additions
Anyone with additional examples can edit a list to add things to it. That can help make it exhaustive, but it can also become too long, and at that point become less useful as an answer.
This is a content-level decision that authors can make at their discretion. Sometimes it's helpful and enhances the answer, sometimes it's unhelpful and makes it harder to understand. It all depends on execution.
So yes, it's fine to provide full or partial lists of examples in an answer to support a general point being made. Whether that's a good idea or not will be revealed by the voting.
Personally, speaking as a post writer, I tend to avoid adding such things. I tend to stick to a minimal number of representative examples in-paragraph (and make it abundantly clear that they're just examples), which can be as few as one, because I find that adding lists to an answer when the list is just “bonus” information makes the whole post harder to evaluate and process. With the torrent of material we produce, simply getting readers to read a post is part of the challenge of writing a good answer. But again, this is just my personal preference, as a writer of posts, and in writing there are few rules that can't be broken for good effect in the right circumstances!
