When we worked on CONTRIB-8031, stronk7 was worred that the block class detection would cause false positives, and he was right.

For example this has just been raised in dev chat https://github.com/QuentinFombaron/moodle-block_point_view/blob/549584b973782981bb2b397fb2b3f18e6d24efdd/edit_form.php#L559

The class is class block_point_view_edit_form extends block_edit_form, so the use of $PAGE there is correct, but we flag it.

(And, it is not possible to rename the class, because Moodle naming rules require the class name to start with the component name - unless you use namespaces.)
