I hope Square doesn't keep deeming certain content unnecessary

The resources were obviously redistributed to new ideas, like Delubrum Reginae, Delubrum Reginae Savage, Memoria Misera, a second BA-like thing (Dalriada), critical engagements (which each involve the same amount of design work as dungeon bosses), the Firmament, ocean fishing, crafter and gatherer overhauls and QoL.

It was not, we had Eureka's 4 zones and BA for SB, but we also had HoH, Tataru's outfit, Allied tribe quest, more EX dungeons, ponctual events, two Ultimates, and possibly more I don't remember were cut.
Despite reaping more money in than ever with ShB, SE didn't give it back to us as content nearly as much as they did in the past.

I implied that 2 of the eureka areas that were cut were replaced with some of the things I mentioned.

None of the Eureka areas had Critical Engagements. What I explained about them involving the same sort of work as dungeons bosses is important to consider. In eureka we effectively just had skirmishes, which is just make a mob bigger and more powerful and call it a boss. There was sometimes mechanic work but I don't think it was on quite the same scale for most of them except the big one in each area like pazuzu. The critical engagements have the sort of mechanics we would expect in dungeons and raids.

And of course we didn't have a Dalriada, a Delubrum Reginae, DRS, firmament or ocean fishing areas. You can argue that level design work from eureka transferred into all of these extra things but the boss fights and mechanics would most likely lend work from the 2 extra expert dungeons and the deep dungeon fights that were cut.

I think that the Allied beast tribes, the ultimate and holiday events were cut because of covid. I am guessing on the Allied beast tribes and holiday events, but if I was a producer it would be a pretty obvious decision to cut "small" things like holidays and allied quests to make up for covid backlog. They've never cut holidays this way so it seems pretty obvious why.

The second ultimate has even had a lot of work on it so it's not really fair to say that this was cut for other content, it's been said it was done because of covid backlog getting in the way and needing to prioritise the expansion.

I have no idea how some little Tataru outfit can come into this. What is that even about?

Sadly this is 100% accurate.

It's a combination of SE is siphoning money away from FFXIV developments, and FFXIV team not hiring more people to share the workload.

And it's showing. Glaringly so. FFXIV is SE's cash cow right now and they're milking it for all it's worth and not giving it time to properly recuperate.
