So to summarize: - It's a slipping hazard until you remove it. - It gets heavy very quickly, making it hard to remove. - Placing it on snow (i.e. too late) can cause it to freeze stuck. In other words you need to anticipate the snow before it starts, you need to repeatedly empty and quickly replace it and it makes the ground dangerous to walk on for anyone during the entire time. Yeah, this is definitely a clever hack and not a useful technique.
