I don't think we need it here, you can implement this on loader side

[peter-spireng]

Issue #95 is still open with "Help wanted" label, so I thought it is still valid feature request ...

[alexander-akait]

We should avoid adding new methods here, if we really need it, we should implement it on webpack side (but I don't think we really need it). We want to deprecated it on the next major release.

And yes, we need to close issues...
