Wouldn't that ventral fin, which protects the propeller, make it
impossible to get a truly low energy landing?

It does have flaps, so that helps, and you can hold it off so the tail touches
first; also, at 34 kg/m2, it's a light wing loading, so the touch down speed
should less than a 15M std class ship.

True dat, but, chicken that I am, the Stemme never gets out of range of
pavement.

No, if the angle between wing chord and fuselage is chosen correctly.
