Could this be written in an {% else %} branch with a somewhat simplified
condition to make it entirely obvious that nothing can be both counted and
deprecated? Something like

{% if not on whitelist % }
{% if deprecated %}
::countDeprecation()
{% else %}
::count()
{% endif %}
{% endif %}

?

Good idea, I like that.

+        UseCounter::countDeprecation(executionContext, UseCounter::{{event|script_name|deprecate_name}});
+        {% endif %}
         return {{event|cpp_name}}::create();
     }
     {% endfor %}
     return nullptr;
 }
 
 } // namespace blink
