It was, in my view, a brilliant way to showcase slightly lesser known sports, with some olympic stardust sprinkled on them.
One could consider the final chance boxing, archery, table tennis and rugby qualifiers to be a not dissimilar construct
I think the IOC has maybe got this partially right - they increase their broadcast toehold and influence without 'creating' another olympics - and did it in a thematic way - what would be good would be if IFs could sit down with IOC, and the continental Games, and work out systems of qualification that made as many events as possible a must see - rankings are fair, and absolutely have a place but they aren't really exciting - qualification competitions generally are (mixed triathlon relay final qualifier, etc)
But the IFs and the continental Games will want their own events given some Olympic 'juice', and I think IOC should, where at all possible, accommodate that too.
Of course some sports, this won't work with - Football, 5x5 basketball, Gold, possibly tennis. But I think there are win-wins here for IFs, including continental IFs, Continental Games and the IOC itself getting more organised on it - and I think the themed nature of OQS shows the way...
For example, what if there were 'final qualifiers/OQS' for all the combat sports, in one place. Not the bulk of the quotas, of course, but just those final few spots in Boxing, Judo, Taekwonso, wrestling, possibly fencing, shooting and archery (or perhaps the last three and modern pentathlon could form a separate, "armed combat" pod?)
Beach volleyball might be the core of, dare I suggest, a beach and sea based final qualifier? Beach Volleyball, Triathlon, Sailing, open water swimming, maybe High iving, somewhere delightfully hot and sunny - Bermuda, perhaps...
some sports don't need that pizzaz on their own events, but I suspect a lot of sports would welcome the kind of three ring circus attention the four urban sports got this weekend.
