bq. Mark the methods as deprecated, document that they will be replaced with a
void return type in collections5, and note that extending the
AbstractLinkedList class is not source compatible with java 21.
Is there a concrete plan for collections5?
In any case it would be good if there was a way current users of
AbstractLinkedList in collections4 could continue to use that. Maybe just add a
second variant?
