You are assuming that Safari didn’t fix bugs for a long time because it “ships slowly.” Maybe some bugs are just complicated and take time to fix. It took Google years to fix the bugs I mentioned earlier (and many others) despite having the largest budget of any browser project and a VERY rapid release cadence.
No a lot of them are pretty straightforward, this is why I’m upset. I’m talking about, like, “SVGs with this feature don’t render correctly due to an oversight in size calculation” not “can you please implement WebGPU in the next release cycle”.
