What *would* be good is a way to design impedance-matched, reproducible layer transitions for high-speed signals. Like a combination of signal vias for both legs of a diffpair, the fanout geometry from the closely spaced pair to the vias, return path vias nearby, maybe a void in the ground plane, etc.
Or for single ended, a signal via with 2 or 4 surrounding return path vias and again perhaps controlled clearance to the plane that's separate from the usual plain clearance.
And once you've designed these and associated them with a net/netclass somehow, every time you add a via it drops the whole transition instead
