The question mentioned by the original OP was "My last question (just now) asked about potential maintainability issues involved with a certain approach to CSS layout." which doesn't appear to be very open-ended, at least from my interpretation.

I'll be honest, I mainly knew what the answer to your question would be, but I tried to put myself in the shoes of a newer user trying to understand what questions a person should ask on SO and was curious of maybe things were different.

And the answer appears to still be some form "you won't know until it's closed".

It's explicitly asking for an open-ended list.

It's explicitly asking for an open-ended list.

If your goal is to come with any reason to label a question a "list question", then I don't think it would be too hard to find a way to label any potential question as a "list question" and have it closed.

A different interpretation would be that the question is about whether there are maintainability issues with a certain implementation of CSS. Which the question being potentially answered with a "Yes/No" where an obviously better answer might provide an example or two of issues that could arise.
