Initiation works in two parts. First, it works to introduce the ball to the child and get them sufficient minutes, hours, and weeks to know soccer well and code thousands of on-field moments and experiences kinetically. The second part is to form their mind and EQ so that those kinetic codes pair with the appropriate mindset and emotion for the most productive and efficient outcome. Both are equally important. Tactics and analytical-technical training are to be at the minimum to allow intrinsic learning to dominate this space. How long does this phase of initiation lasts depends on when one starts. The later in human development, the more time it will take and possibly the less impact initiation will have. The impact of initiation may diminish when started at an older age because a young child is free from the subconscious turmoils of an older child. Play is their environment of learning, and they know not else. That is why trying to extrinsically control or influence this phase works against the desired outcome.
