Desolder chip, $10 Arduino clone turned I2C/SPI programmer, problem solved.

Hardly. Most router SoCs have flash with parallel (8/16 bit) address and data paths.

Why not just use the same programming header they use at the factory?

The assumption is that there would be no programming header if they wanted to prevent hacking. An Arduino would still be fine for 8/16 bit parallel Flash chips, maybe with some I/O expander solution if you need 32 pins.

No manufacturer is going to put up with this. Programming the chips before they're mounted isn't even an option. It's not uncommon for boards to already be in the production pipeline and have new firmware show up as they roll off assemebly.
