Class file structure and simplifying integration into a framework

[BrainforgeUK]

I've been looking into integrating H5P into another framework - an alternative to existing Wordpress or Drupal integrations.

To address the issues I've encountered in this can I suggest the changes:

(a) Change all private class functions / properties to protected.
This makes it easier for the framework integrator to extend classes, creating overrides.

(b) Split file h5p.classes.ph into a separate file for each class.
Makes it a lot easier to read and find things.

(c) Add the following line to the top of each file i.e. use namespacing.
namespace h5p_php_library;

Screenshot of the framework class structure I am pursuing.
Long-term this will create maintenance problems with porting changes from github into the framework.

How can I integrate H5P with CodeIgniter 4?
