Blurry strokes and zooming via scale transforms

I recently had a similar situation, but then because certain properties were calculated-via-binding and the resulting value was not "snapped" to good values either.
This resulted in my suggestion to allow custom calculations in bindings, which would then snap the value.
And transformations on such values have the same effect of course. I was wondering, similar to the binding suggestion, would it be possible to apply a snapping transformation as the last transformation?
