"I'm not exactly sure how my comment is not as useful as the others just because I have an opposing opinion."
Saying it's an "unbelievably stupid UI design" isn't in itself useful, in my opinion. There are other people who seem to say it's a good idea, so if it just comes down to taking one person's word for it vs. another then you and the people of the opposite opinion then we're right back where we started. It may not be a good UI design, but I think there are ways of collecting data on this other than reading these type of responses.
"And distinguishing between icon and label is not a good solution because that makes the selection area too small to be useful (especially in list and compact view) and you always end up clicking on the label the second time anyway because this is big and easy to click and better symbolizes the file you're trying to manipulate."
This is one reason why I'm suggesting that IF someone were to implement this that the only clickable area should be the actual text, not the empty area to the right of the text (whether that empty space is technically part of the label or not). In Windows it seems that the entire cell area to the right of the icon is considered "the label", so it's very easy to put it into rename mode even if you don't click on the icon or the text. These kind of differences may (or may not) make a difference in your bad experiences on Windows in the past.
