I did. For about 2 days.
The only thing I use are push sticks for narrow stuff. Those and an adjustable, fence mounted strip of Lexan that serves as a hold down and (minorly) hold in.
When I was using a radial saw I used featherboards a lot but find they are hard to use on my cabinet saw due to the webbed bottom table surface (hard to clamp to).
I do mean to rig a splitter for my zero inserts. Someday.
