What are the advantages of using an API or sandbox like runkit to restrict access to critical functions in PHP plugins?

When developing PHP plugins, it is important to restrict access to critical functions to prevent unauthorized users from making changes that could compromise the security of the plugin or the website. One way to achieve this is by using an API or sandbox like runkit to create a controlled environment where only certain functions can be accessed. 

// Example of restricting access to critical functions using runkit

// Define the critical function that should be restricted
function criticalFunction() {
    // Function implementation
}

// Use runkit to disable the critical function
runkit_function_remove('criticalFunction');
