Artefact issue with Helicon filter 5

As I already wrote, I believe that for you, and for landscape photographers generally, the artefacts in foliage rendering are concern, because for you the trees and and foliage are very often really important, or even main, part of composition.

But, based on thousands of pictures I saw (on pictures hosting servers), taken and published by different people (novices, enthusiats and pros) using XPro-1, I believe that main user base are people who use trees and grass as backround only, not as the main theme of picture.

So for these people (including me) occasional artefacts in backround foliage of picture (often overpowered by bokeh btw.) are not big issue, because it doesn't influence the overall impression of their pictures.
