Revealing number of unpublished content in reverse reference

If I query referenced entities reversly (reference field is on referenced entity, not current one) it will return array of all entities - published one are returned as object, but unpublished as null:

```
"reverseProductIdProductTerm": {
"entities": [
null,
{
"fieldDate": {
"value": "2020-06-01",
"endValue": "2020-06-30"
}
}
]
}
```

I consider reveling number of unpublished entities as low priority security issue.
