Yes that makes sense. I guess that's a general problem that any locations with lines getting close together can get interpreted as a low illumination area from shading.

And then if you are actually doing shading aware spacing that might be even worse because then you'll have some areas with higher density from shading and some with higher density that is not from shading.

Here are a couple of results, first with "tightly packed" lines where it tries to insert a new one as close as it can to existing ones, and the last 2 with sparser filling:
