But there is no good reason you can't do that already. Hardware engineers have just been fundamentally unserious about computer use going on 20 years. The PCB design you could do in 2000 already, but now it's still PDF datasheets, people drawing footprints and connecting RX lines to RX lines.

I gotta give the hardware team credit for programmable pins on μc though. It means you just need to bring the pins out to pads and do whatever, instead of each pin has a fixed function so pin 14 MUST go to the next thing. (Within reason; vcc and gnd can't move).
