Well, this is Broncos forum so that's why you're hearing about it here. And it was reported in the QLD newspaper. A google search tells me the Knights were likewise reported on the Knights forum and in the Newcastle press.
As for us getting Covid over and done with, that would be fine except many of the cases - in other countries, particulaly - are reinfections. In the UK, as many as 15% of cases so far are for the second time. So much for the myth of enduring herd immunity. It's fleeting, at most.
If Omicron is always very mild like a cold - which it isn't - and we know it causes no long term effects (cardio, neuro, pulmonary, etc) - which we don't - then maybe getting it over with to gain a short term immunity against immediate reinfection might have merit. But at the moment we can't tick any of those boxes.
