To add to your argument, they actively took away the gating from extreme primals and raiding, and stated that gating content was bad for accessibility.

They took away the gating because you had to do nearly all of the older Extreme Primals to unlock the new ones, when at the time there was little incentive to redo them besides Ponies and Furniture since none of the gear besides the Garuda/Titan/Ifrit Jewelry were relevant item level during their patch. Say patch 2.4 just came out and you wanted to do Shiva EX. You want to try it out but you find out that you need to beat Ramuh EX, but wait a second! If you haven't done Ramuh EX yet you had to do Mog EX and Leviathan EX. So if you wanted to do the newest content you had to complete content that was 2 patches old, or in other words, 7 months old!

Depending on how your server's PF was, this process could've taken a while since many of those EX fights were a nightmare with new people along with the fact that the people who wanted to farm that content already got what they needed and didn't have to do it more. Ramuh EX required (at the time) high DPS to progress past the add phase. Even if you had the DPS to get past the ultimate many people failed tethers happened since they had a Pyretic-type effect. Mog EX was considered a PF nightmare with the fact that Voice Comms was basically a requirement to make sure the Moogles went down evenly, ensuring you either didn't push phases early or caused a wipe. Mog EX was also rarely seen in PF since it didn't have a mount attached to it, meaning most people did it only once. Leviathan EX also punished people who didn't have their camera spinning to know where to avoid being dunked.

There's also the fact that there was very little connecting these fights besides the requirements.
