Is there a mechanism to delay a reclaimed Child ID be allocate to a new Child device?

Thread does not provide a mechanism to control how reclaimed Child IDs are allocated.

OpenThread will attempt to cycle through the set of available Child IDs before reusing previously allocated Child IDs.

	// pick next Child ID that is not being used

	mNextChildId++;
	if (mNextChildId > kMaxChildId)
	{
	mNextChildId = kMinChildId;
	}
	rloc16 = Get<Mac::Mac>().GetShortAddress() | mNextChildId;
	} while (mChildTable.FindChild(rloc16, Child::kInStateAnyExceptInvalid) != nullptr);
