It's about this suggested edit I made, and the suggestion to create a new answer to the question.
In this case, the change I made from
IEnumerable<> on the private methods was only to fix a compilation problem, so that I could move the
.ToList() call to another position, which most likely improved performance.
This is in the discussion (the question asked by that poster) a little minor and I thought it was not worthy of a new answer. And since I don't have enough rep to add a comment to the answer, there is not really another way to add this information to the answer.
Is there a clear answer as to why this was rejected (i.e. the guidelines to edit, or repost an answer with some edits)?
