I am aware the mining fees for remixes by new entrants to the pool.

Your example only focuses on the benefits localized to a single remixer from the round without mentioning the downsides are externalized to new users. If all 5 participants from a round decided they wanted to remix for free, then they all become "stuck" indefinitely until the pool grows bigger with new users to pay for their mining fees.
