And what is WiGig? That is like a disbanded org since 2011 or 2013? It is now 802.11ad, and I suppose it has nothing got to do with Apple calling off because it is pure garbage spec. It is very likely any development now would be 802.11ay, the successor of 802.11ad, trying to fix and get a properly 60Ghz wireless working. It is still in draft stage and I hope they get it right this time.

WiGig was an organization (absorbed by Wi-Fi Alliance). 802.11ad is a spec. 802.11ay, the successor of 802.11ad, is a more-or-less straightforward extension of 802.11ad: it supports wider channels and more antennas.

802.11ad is a decent spec, but mmWave is poor technology for indoor use. Among other challenges, mmWave signals cannot pass through walls. So you'll only get coverage if you're in the same room as your AP. Nevertheless, 5G is renewing interest in mmWave technology. I think we can speculate Apple was interested in 802.11ad/mmWave, because they listed many job openings for mmWave engineers (unless that was an elaborate ruse to throw off the competition).

I'm guessing they came to the conclusion that mmWave WLAN is still not ready for prime-time. Almost no Wi-Fi APs support it, the signal cannot pass through walls, and most consumers have no use for 4.6 Gbps data rates (most of us have 15-75 Mbps connections to our ISPs).
