Why doesn't APFS always clone files when copying?

For example, why doesn&rsquo;t the cp command automatically clone files without requiring the -c flag?

That and implementation detail of the cp command, not an APFS feature.If I had to guess why, it would be because there are many cases where cp could not create a clone, such as copying to a network file system.
