I'd argue it would be unethical to not do so. I can see where it may lead to false-positives, but in those instances, it's better to be safe than sorry.

A reasonable and responsible approach could be to instruct the child to seek a safe adult around them to discuss any material that may be harmful.

For my own kids, I think I'd prefer it not to instruct the child do do anything in any circumstances, unless they explicitly ask how to do something. In cases of health emergencies, I think it's important for my kids to be able to call 911. Maybe these are decisions we can have in the parental settings, so parents can make that decision.
