Everyone scratches their own itch. There is value in multiple implementations when they explore different approaches. This just means either a "perfect answer" has not been found or that the journey itself is seen as worthwhile.
To be fair, they did at least mention an alternative direction to pursue, so it's probably more useful than many of the dismissive comments that I see. I'm not convinced every comment on a project needs to be supportive of the project and its goals.
