Answers converted to comments should retain upvotes
In most cases I would flag as 'not an answer', the answer would be converted to a comment, and everything would be right in the world. However, in this case the comment-answer is an important caveat to the accepted answer and has a number of votes because of that.
Is there any way to convert an answer to a comment while not losing the information captured by its votes? Should there be?
Edit: To be clear, I don't care about the rep of the user who posted the comment-answer. They should've posted a comment. I do care about preserving the community's recognition of the usefulness of what they said. That's important information for future visitors. Something like Jeremy's suggestion of converting the comment-answer score into pure comment score would work, but feels a bit weird.
