Switching to road tires/wheels on my gravel bike

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Nothing like dropping in a spare wheelset and finding out the rotors are about 1-2mm different spacing, and now graze your brake pads.
As an alternative, you can just add shims to the rotors on the wheelset that is mis-aligned.

Yup, but you can only shim out, so you shim whichever rotor is further in to the position of the rotor that's further out.

Darn it! If only there was a way to change the gear ratios on a bike while riding...
