The short side ones are for programming - the FTDI header on one end. On the other end Boot0 is for advanced flashing, and A0~3 are just more IO pins. I don't think it's worth the extra 0.2" to make those breadboard friendly, but at the same time, I think it's better to leave them available. Like how the Arduino Pro Mini has a few pins that aren't in line with the others. At least these are aligned on the same grid!
@allObjects - I think you and I are the only ones who love EEPROMs and FRAM and use them all the time - I don't know that that's a feature the rest of the Espruino userbase would care about.
