This changes the way license usage is calculated. Previously the licenses would prohibit enumerating more than what was licensed. This had the benefit that the backup engine was unaware that more items exists.
However, this also prevented filtering items, as the enumeration happens before the filters are applied.
With the new approach, enumeration is applied without imposing limitations, but actually reading the items are limited. This allows filtering unwanted items, and they will not count towards usage.
The downside of this approach is that the backup will contain empty "folders" that could, at a glance, appear to contain everything, but are in fact just empty folders.
To mitigate this, the warning message now explictly mentions that some folders may be empty.
