Add filled zones for Edge.cuts

Layout
1

I was looking at someone else’s PCB to better understand ‘add filled zones.’

Owing to the help I got from this forum, I was able to finish designing the first iteration of my first PCB for now.

But I noticed in the example PCB I was looking at had a filled zone defined by the edge cut outline. (Photos below)

It made sense to do filled zones for either front or back layer of Cu layer but I am not sure what it means physically to add filled zones for edge cuts and its possible benefits.

Edge cuts is a non copper layer. A zone covering all the pcb has no meaning for me in this layer. I cannot see the effects it makes.

It may be accidental, or maybe it was imported from another package ?

Don’t know what is the sense of a filled zone in the edge.cuts layer, but kicad allows creating such a zone.
It can be useful in other layers, as silkscreen or eco, drawings, etc.
