Could argue that other Eureka areas were "more of the same". More NMs, another big boss that drops an important item, a level cap increase.

Nice of you to mention quests, since Eureka had them and they even had real story, unlike IS.
V&C have the real story I suppose.

Most of the regular content has rare minion drop and some mount as a reward, this isn't meaningful progression.
So then neither is most of the loot in Eureka.

I have no clue what special actions of IS you mean
All the ones to feed animals, sow seeds, gather things, the V&C dot, mitigation, heals and rez. They aren't as spectacular as logos or lost actions, but they involve similar development. We could argue all the individual items and plants we pick and grow are using similar development work, because icons are made for them.

You do IS once and you're done, same with V&C. You do Eureka relic from start to finish and you have 14 other relics to get.
I agree. Although it does depend. You have to run Variant dungeons multiple times for the mount and can farm them for the minions and other rewards. You have a lot of Criterion runs to do if you want the mount. But I agree it's not the same as having lots of relics to do making the content replayable. They are also really boring to repeat, especially Variant dungeons (I gave up and just bought the minions).

Also you did not account that Eureka takes much longer first time you do it because of leveling.
I did. It only took me a few sessions of 3 hours per area, when it was current. I did it extremely casually between other content I was into, yet enjoyed every second of it.
