Adding a new magic method is not a backwards compatibility break. The PHP documentation on magic
methods states:
"Caution PHP reserves all function names starting with __ as magical. It is recommended that
you do not use function names with __ in PHP unless you want some documented magic functionality.”
Any user implementing their own methods prefixed with a double underscore is taking the chance that
their code could break in the future.

PHP 7.4 introduced the "get_mangled_object_vars()” as a result of these concerns.
