Usually due to some kind of physical or intellectual disability or delay, for whom the extra year of maturity and preparation makes an enormous difference in their ability to work in/closer to the "typical" range, and thus to be more successful in school. Of course, though, there will always be people who look to take advantage of such leniency just to get a perceived edge over other students.
I'm a special ed teacher, and not the OP, and research has clearly demonstrated that kids with intellectual disabilities in particular, need to be in school on time, as they benefit from the intensity of a full day of school during those early formative years. In addition, Federal law guarantees children with significant disabilities the right to public education until 21, so when parents redshirt kids with ID, they are denying them a year of post high school education which is when crucial vocational skills are developed.
Most school districts address this by essentially disallowing redshirting for kids with ID by refusing to provide services, or limiting services during that year, which means that almost all kids with ID go to Kindergarten on time. When parents of kids with average or above average cognitive skills redshirt, it can place kids with significant disabilities in the position of being both significantly younger than some of their peers plus the disadvantages that come with their disability.
I can see pros and cons of redshirting from the point of view of kids without ID, I'm not saying the decision to allow or disallow redshirting should be made solely because of the needs of kids with Intellectual Disability, but I will say that allowing redshirting is not in the best interest of kids with ID.
