@idefix37 Sure, I take your point, I don't want to be throwing the baby out with the bath water. I'm generally thinking about non-orographically induced convective precipitation when I talk about the merits of extrapolation. But do bear in mind – models can be pretty bad when it comes to orographically induced convection.
Frontal precipitation is a very different story however, and I would most certainly agree that a high-resolution model will beat extrapolation in a frontal situation over complex terrain even at short lead times. I'm not sure what the Swiss approach specifically is, so I won't comment on that.
With convective showers though, the terrain won't matter as much. The triggering is a bit less random, sure, since the model will understand the thermal properties of the orography to some extent. But terrain induced resolved convection still has a ways to go, especially because of a problem known the "grey zone", which is emerging in sub-kilometre resolution limited-area models.
All the same, if anyone knows their way around complex-terrain NWP, it's the Swiss :)
