Please take a look at this questions. It was made community wiki sometime after it was posted. The answers that appeared before that are still not community wiki. But I guess they should.

What do you think about this and what should be done?

In order to make up- and downvotes useful, let's see upvoting this question means "They should be made cw" and downvoting it means the opposite.

I think that in cases where the question is meant to collect a sorted list of responses (or other questions that "should have been community wiki to begin with"), like the example you provide, the answers should be community wiki for reasons discussed elsewhere.

In cases where the question got converted to community wiki automatically due to a large number of edits, but is still a mathematical question with a definite answer, I see no reason to automatically convert the answers, and doing so may cause people to feel that they are being deprived of reputation that they 'earned' by providing a helpful, informative answer.

Once a question has been converted to community wiki, previous answers remain wiki or not depending on how they were marked when written.

If you see a question that should be made community wiki, you can flag it "for moderator attention," so that a moderator can convert the question+answers if appropriate. You can also comment on the answers so that the people who wrote them can change them to wiki. The first is likely to be faster.

  • $\begingroup$ @Charles: You're right, the existing points are not lost. What I meant by "deprived" is that the answers were written with the expectation that they would accrue reputation for votes, and that converting them to CW afterwards violates that expectation, and can be seen as depriving the answerers of something they feel is deserved. $\endgroup$
