Weird isn't just visual. Weird is whatever strays from the norm. Weird is relative to the current state of the world.
You can have weird principles. They should be things people can legitimately disagree with.
You have to remember Obsidian was very weird when it launched six years ago. Local files, malleability, backlinks, graph, even Markdown syntax... these were not as widely understood and accepted as they are today.
That's why I spent so much time writing essays like "File over app" to try and explain our choices. The goal was to describe why our weird ideas should be normal, and it worked!
Now the world has somewhat caught up and accepted those choices, so it's time to find the next frontier of weirdness.
