I like this idea. Hiding the seam in a crack or sharp corner (convex or concave) is already a thing, and your idea builds on that.

I'm also curious what it would do for part strength. If you offset the zig-zags from layer to layer it will not be as pretty obviously, but it should act like offset bricks in a brick wall. Worth exploring (but I don't have the equipment to test part strength).

One effect of this would be to make the print dramatically slower though, you would never get up to max speed due to all the cornering.

You could do this sort of pattern already while modelling (though that offset version would be very fiddly). Less practical than the slicer but useful for a quick proof of concept.

Thinking about it some more, this is not that far from the existing fuzzy skin pattern already in slicers, and I believe that the relatively obscure slicer IdeaMaker does allow to apply arbitrary textures as height maps on the sides of parts. That could be another way to explore this.
