Read it more carefully. PWAs are no longer supported, even in safari. Any old PWAs that were already in the launcher just become web links. They happen to open in safari, but they are not PWAs, and no new such links can be created.
This is just a way to not delete the old links from the user's launcher until they have had time to create new bookmarks in the browser of their choice.
If you are going to argue the this somehow advantages Safari, you aren't being serious.
