Question about checking for zero-area-faces?

[humanbeingZ]

Hi! Thank you for this awesome repository.

I have some textured models obtained using photogrammetry software. I plan to use xatlas to repack the texture atlas. However, I found xatlas complaining about a lot of faces with zero area. And the resulting repacked model contains a lot of artifacts due to this.

I read part of the code and found faces with zero area are ignored in this line. I commented out that part and found the program works just fine. And resulting repacked model looks good too.

So I'm wondering, why do you explicitly check for faces with zero area and ignore them in the first place?
Can I use this code the way I did?

I'd really appreciate it if you could answer these questions. Really thanks!
