Hard to imagine anyone would do this. Even though the nomograph
indicates you can run 750 mA thru such a trace, and only have a 10degC
temp rise, there are several "other" things to worry about. Trace series
R producing IR drops. Digital noise in this narrow channel. Inductive
effects of narrow trace width at hi speeds. Impedance issues. On and on.
