It's not something which I did invented myself, I just took the
implemented syntax and described it. Also what do you want to remove?

A graph is not a list, so for describing it you need to specify each
connected sequence (aka filterchain), the current syntax seems quite
convenient to me, the alternative would be to label every link in each
filternode.
