> I think this is domain specific, and hard to find a default that will match all use cases, that’s also why ParaView can store custom default properties.

I fully agree with you! and on or off it will be more suited for one or the other, nevertheless the crinkle would not ‘look’ like there is an issue on the mesh for any application where on the other way around yes… and

> That said, if you consider that those edges should not be there at all, we may investigate why they show up

oh for sure they should not show up, I am guessing it is from some form of projection of the other nodes of the cells where the plane is cutting them, it creates this ‘phantom’ edges that are not supposed to be there and a lot of people thinks there is an issue (reason of asking the default behavior, as people that knows about overwrite the default value). if the lines are removed and we can keep the ‘not crinkle view’ this would be even better but not sure how complex this would be.  
FYI, this comes quite ofter:

@nicolas.vuaille do not hesitate if a mesh to test this would help, i can provide one. also if necessary i can make an issue (but i guess there is a lost somewhere issue already created for this, i remember asking personally about this a bunch of years ago while doing my phd)
