Description

If the $enableUnsetFeature parameter is true, array_merge_recursive_overrule you can unset values from the first array.
The phpDoc says:

* @param boolean $enableUnsetFeature If set, special values "__UNSET" can be used in the second array in order to unset array keys in the resulting array.

But in fact keys are only unset if they don't hold an array value. I see no reason why this should be like this. There should be the possibility to unset array values.

Although this feature is not used in the Core at all, we can't change that behavior easily since this is public API.
Hence this would require a deprecation period of at least two versions first.

I don't agree. It just changes the feature in a way to behave like it was documented.
It's very unlikely that someone used __UNSET on an array value which he doesn't want to be unset. So I don't expect anything to break.
