I’m not a content creator and I don’t really care about Ladybird. I use Safari.
I’m just pointing out that browsers have decades of legacy cruft from mis-steps deciding what the web even should be and someone smart can carve out a path to covering 90% of use cases in 10% of the effort and code. And there are the huge organizational costs Google and others pay that a small organization doesn’t have to.

The defeatism among engineers is sad
