Just saw that you added a comma in the last part of the arrays (and also in your PR towards mine).
Are you sure this is correct?

-   'protected'
+   'protected',

Yes 😄

The comma after the last array element is optional and can be omitted. This is usually done for single-line arrays, i.e. array(1, 2) is preferred over array(1, 2, ). For multi-line arrays on the other hand the trailing comma is commonly used, as it allows easier addition of new elements at the end.

and

When splitting array definitions onto several lines, the last value may also have a trailing comma. This is valid PHP syntax and helps to keep code diffs minimal.
