Please don't take this as an attack, but you've said that before for previous updates as well. Mojang has proven historically that the first snapshot has the bulk of the content, the second snapshot has 'A' feature or two, and the rest are bug fixes. IF by some miracle they release something new in the next four months (which is my estimate for how long it will seemingly take them) then I will admit I was wrong and be absolutely shocked.
...I'm just not seeing it, sorry. Granted that *most* of the stuff comes early in the update, no question there. But there's generally a trickle of other stuff afterward too, not counting minor updates like Frostburn or Buzzy Bees. In the case of Village & Pillage, we were left guessing for quite some time what the villager work stations would actually do.
And in the case of Update Aquatic, as I said before, pretty much as soon as we got everything mentioned at Minecon, pre-releases started. Granted, we don't have everything mentioned at Minecon for 1.16 yet! But it's closer than I remember happening in the first couple updates in 1.13 and 1.14.
I will admit that Mojang has disappointed me in the past by leaving things unfinished that I predicted more detail for, though - notably the Pillager Outposts, which still seem way too bare. Like other mortals, I sometimes guess wrong.
In any case, we'll find out soon enough! Thank you for your civil tone in disagreeing.
EDIT: Oh! Perhaps you're referring to some things I said about 1.15? Yes, you're right that I dropped the ball there, I didn't fully grasp at first that it was intended to be a minor update.
