I think it depends if a lot of pages start breaking. Right now it's not happening at scale, but I don't see them having any reason not to refork Blink if more "only tested on Chrome" sites start breaking on Safari. I'd expect them to maintain all strategic decisions if they did refork, including disabling PWA features; there's nothing that says they have to enable PWAs just because they fork from Blink.
