OK it’s a little faster. But consider : 1 millisecond is 1/1000 sec. We often photograph birds in flight at 1/2000th sec or 0.5ms to freeze the motion. So the tip of a bird’s wing will move 28 times as far during sensor readout using E-shutter compared to mechanical shutter closure.

That's not true. Mechanical shutters have rolling shutter too. The mechanical shutter doesn't completely open and close in 1/2000 second. There's a slit that travels across the frame. No part of the frame is exposed for more than 1/2000, but it takes much longer than that for the whole slit to cross the frame. That's why the flash synch speed is usually about 1/200 or 1/250.

Of course this affects different parts of the wing depending on how it interacts with the line-by-line readout of the sensor. I think a 14ms readout will still show very significant rolling shutter artefacts and distortion. The only complete answer is global shutter (whole sensor read out at the same time).
