That they are added in an init function is an indicator that they aren't
really dynamic.

That's true. However, another indicator is that anything that does not have a struct field is also not really static. :)

So right now, child properties are all "dynamic" in this sense. This could change when Anthony converts buses to QOM. The bus right now is embedded into the HBA's struct, is not a pointer. This likely would change when buses are QOM-ized, but then the bus would indeed be a 100% static child.

I think having a child property that can be NULL could be

I think Anthony convinced me this is not the case (unlike links). Even if buses and similar objects are changed to pointers because the implementation needs that, those pointers should never be NULL (or if they can, the child property should not exist when they are NULL).
