Yeah, I think the castellations have been good with the Pico - I forget whose idea it was now, but it was someone on this forum I think :)
For the snap-off, my only worry would be that if someone soldered pins onto it and then put it into breadboard, having a snap-off bit might make it more likely to break, especially if the PCB was thin :(
