I am still stuck on the statement "no roof overhang looks more modern"... I really like our roof overhang - the same house without a roof overhang looks much more "cheap" to me. But that is subjective after all.
I would put it this way: with only 10 cm of verge-side roof overhang (10 cm are relatively inconspicuous in this dimension, it almost looks like "hemmed"), 50 cm on the eaves side (which is not an unusual size in absolute terms) appear relatively like flashy claw nails in direct contrast.
We have a 30° gable roof without overhangs, but with a clinker facade.
However, we invested in verge tiles (for Braas Turmalin) and a fascia board cladding made of zinc sheet to avoid having to paint so often.
Everything warm and dry – and here in the North the rain also often comes horizontally
To protect against rain or sun, you probably need about 50 cm of overhang.
What bothers me much more here are the windows on the upper and ground floors that are not aligned with each other.

However, with , one can recognize a regularity, so an intention. Possibly to depict exactly the "other." It certainly is not to everyone's taste, but it is probably meant to stand out from this boringness.
If the roof overhang is also supposed to protect the facade from moisture, then a larger overhang would have to be realized on the gable side than on the eaves side. 10 cm already looks somewhat "cheap," and furthermore, I share 11ant's assessment regarding the appearance with different dimensions.
For myself, the advantages of a larger overhang are already important. Our half-hipped roof has about 55-60 cm. The facade only gets wet during driving rain, and the windows almost always remain dry.
