When some people see a child without parents in arms reach, they assume the worst and report the situation. Many parents live in fear of being perceived as negligent, and for good reason. There are some real horror stories about parents getting in big trouble for situations no one would have batted an eye at in the 80s. Even if a kid has earned trust and the parent knows the kid would be fine, there is still the looming threat of someone reporting negligence.
If children do not learn independence, they will not be prepared and will carry a lot of anxiety when they need to be independent.
