Is there any reason you didn't go with a ftdi or similar
serial-over-usb solution? I imagine most if not all uses of the
serial port are connecting it to PC via a usb dongle.

yes, but there is still many other uses for the board where the other
side might not be a PC...

Very well said! In addition, we spend a lot of time trying to keep the cost down. This idea was rejected over a year ago and nothing has happened to make that decision any different.
