They're gone since commit a61383f7ab (qdev: Legacy properties are now unused internally, drop, 2025-10-22). I'd avoid the term. I believe the new pointer is always null for now. It will be non-null for properties created in new, QAPI-aware ways. What about something like Add a const pointer to QAPITypeInfo in ObjectProperty. NULL for now, but future patches will add means to make it non-null. The QAPITypeInfo will then be used by QOM introspection to tie the property to a QAPI type.
