I had full front to back routing on CAAD10 Disc with cable pull discs and never had any problems when calipers were adjusted properly - i used CX77 calipers and they were far more responsive and modulated that Sram Force CX1 HRD
Also did the same on a Trek Crockett - no issues whatsoever
It’s the gear cable stop that’s gone though. I know you can run full outer for that too like most CX and MTB. Concerned about extra friction for shifting though
