I agree with your OTP stance, not worth the bother!.
And without hardware serial it is trivial to do in hardware, Nigel. It just takes more wires... I was actually looking for justification for YOU. You see, I can do it in HW with 3 wires. I can do it with a UART with two.
If a railroad hobbyist simply wants to control some lights, He sure as hell does not want to learn to program ANYTHING on top of learning to read schematics and solder if he does not HAVE to.
