Well, nobody seems to know anything about this. I submitted a new version of my app to the AppStore yesterday with BOTH applinks and wecredentials in the associated domains.
applinksis for universal links
webcredentialsis for web credential sharing
If you just want universal links, use just
applinks. For info on this, see Enabling Universal Links.
