Even in this case, however, the stdClass specialization would have dynamic properties implemented in a way which would allow an escape hatch for user classes via extending stdClass. We wound up with the attribute approach instead, which means that the logic for dynamic properties, as well as the allocation overhead, still has to exist in all userland classes. All approaches however, came with stdClass working as expected out of the box, and a low-effort, forward-compatible escape hatch for those rare cases where dynamic properties are needed on custom classes. This is because PHP's dedication to stability IS, AND REMAINS, steadfast and fanatical. -Sara
