The variant with the cuts in the corners was denied to us because then "the maximum length becomes too large." So, we were only given the choice of whether the cut should be made to the left or right of the door.
Well, whether that is consistent, I cannot judge.
At least it could have been positioned elsewhere and covered with a gutter.
"Could have" is unfortunately of little help.
By the way, the damages on our side appear exactly at the
corner , not in the middle – whereby the main cause for us is the precast lintels that have not yet been properly separated with expansion joints. The length on the eaves side is also 14 m; only on the eaves is the brick cladding continuous over more than 14 m. The window cladding precast lintels (into which the cladding bricks were concreted) are attached/hung on the surrounding ring beam, since the roof there is partially open up to the ridge, meaning there is no ceiling.
The defect is currently still being repaired; the lintel beginning also needs to be separated in our case.
This is how it started:

After the first – inadequate – attempt of merely re-pointing, it soon looked like this again (the gable side is at the front):

(I had already complained about and documented the missing expansion joint at the top at 14 m during acceptance; it was placed under observation. Now, after 2 years, the defect is showing. The general contractor (GU) is willing to fix it; the subcontractor from the GU is still a bit incompetent in the implementation. So far, only the damaged, meandering joint at the front corner has been separated. However, I believe that separation is also required at the beginning of each lintel. We are currently working on that.)
Conclusion: An expansion joint is necessary.
