Browsers have been historically the biggest and most difficult projects, so hard to say why it wouldn’t be. When they can start promising 20k bounties for segfaults, they are getting close.
As someone who has first encounter with the ladybird - why is it exciting?
And how could ladybird attract so many sponsors for such a project? Why wouldn't they fund Firefox instead if they want to achieve some diversity in browser engine field?
Given how few generally usable browsers (3 with different skins) there are and how huge they are with basically required company backing for many employees... How is that a trope?
