I don't know the answer to your question, but I'm always willing to speculate.
In SSP stippling is prohibited by A.1.4.9
ESP just refers you to 8.1.6 & 8.1.7, which are the allowed and prohibited modifications for all divisions, and it does not mention stippling.
Rule 1.2.2.2 says All equipment must be practical. This is the guiding principle for everything in IDPA. I think it's perfectly reasonable and practical to stipple an EDC CCW.
So it seems like stippling is ok in ESP and CO.
