What happened here? This seems totally and utterly irrational. Is Apple trying to kill this technology? It already was behind a feature flag in Safari TP, which means no normal user would've been able to use it. But to remove it completely, even as an experimental feature? Seems rather suspect to me. Maybe Apple just doesn't want this technology to succeed after all. It's the last missing piece to seal the deal of native vs. Web apps; in favor of the Web. Maybe they just don't want this to happen. Google with Chrome and Mozilla with Firefox seem to be able to get it working. It can't be that hard. But Apple can't?
