Early versions of Trianglify supported noise addition using feTurbulence but I ultimately removed it because of some of the rendering inconsistencies mentioned in this thread, alongside performance issues on certain platforms (you would think that generating 2d monochrome noise would be pretty cheap in this day and age, but it must be part of the SVG stack that never saw much optimization because it would absolutely lock up rendering for several hundred milliseconds when applied to even moderately sized viewports).

Of course, this was all back in ~2015 so the landscape has definitely improved, but not quite to the point where I would consider adding support back in.
