One measure of the problem(s) of list questions in general is if the lists have a (single) natural and objective ordering, or if the ordering is subjective and/or dynamic. A question could also specify the desired ordering, and boundaries limiting the number of relevant list items are helpful too under the current SE software. For example "Which US Senators have the longest last names? (top-10)" might work, but it's probably not particularly realistic.
Thus natural/technical evolution causes valid technology-neutral questions to become less valuable, with outdated answers misleadingly labeled as best or accepted. The problem isn't with the questions but with how the system is treating the answers:
Yes, a potential solution to this challenge is to make the answers a Community wiki answer, which invites collaboration and removes the motivation to get an answer marked as answered quickly. While lists have an enhanced requirement for collaborative behavior, but I'm not sure the existing Community Wiki mechanism is viable long-term solution for lists.
The use case where a community wiki answer fails specifically for list questions is about the ranking of items on the list. I think the best answer for lists would be a way to have individual list items remain as individual votable answers, but have the system's default presentation of the answers is more unified for lists, so that the answers don't compete with each other for points, but where a compact list order can be shown with score determining the order.
Furthermore, the SO model of single-dimensional votes becomes less useful for lists. Take a hypothetical question: "which media outlets are best for quality." Sites like Media Bias/Fact Check score their lists by at least two dimensions, Bias and Factual Reporting. This leads me to think that the so-called "lists" this question is describing should really be presented as multi-column sortable tables.
To illustrate the above point, it may be useful to compare Wikipedia list pages like List of fact-checking websites (inflexible and only limited value) vs List of states and territories of the United States by population density. Of course, a multi-column table may not come easy on SE. This might be an area where a single link-only answer (or iframe) pointing to another collaborative site like Wikipedia may be the best solution short term. Perhaps creating an iframe style answer would best be limited to moderators.
