I think that’s misleading since Safari’s development is not generally discussed outside the occasional WebKit blog post and the rare Safari developer on Twitter who may or may not rightfully ignore any questions/arguments. A lot of features are implemented late and incorrectly. I think that the first Safari version that supported PWAs was so broken that many had to manually exclude the browser in their support detection code.
