This is how I see the issue. Forget the maze pattern (it is pronounced in LR/ACR that does not officially support the 7D, but much less in other production converters) it is unlikely that you will see a maze in your images. What you might see is noise, rectangles. These artifacts can show up in your images. The artifacting will be more likely to occur as ISO increases. It may be more likely to occur if you under expose your image and then bring up exposure in PP.
If you want to see what can happen, I would suggest shooting some portraits at ISO 400 or 800. You might find the texture of the skin ruined in some of the images with the artifacting described above.
From my perspective, the bad thing about this problem is that you just don\'t know which images will be affected. So you start shooting a series of portraits or a family event and you just don\'t know which images will have enough of this noise/artifacting in them to make them of marginal quality.
DPP is OK at reducing the problem. C1 can work around it to some extent. The new beta of Bibble seems to be able to minimize the problem also. I am hoping that the production release of ACR/LR will minimize with the problem when it is release.
I\'m still trying to understand how to avoid/minimize this problem. Things that seem to help ... shoot to the right, RAW converter can reduce, lower ISO can help. My current 100% fix is just shoot critical work with my 5DII.
