I'm not really sure I am buying the difficulty argument. Pretty much every game I played with more difficult content devolves almost immediately into meta obsession, streamer worship, BiS lists, rotations, 3rd party tools, parses, etc. For a lot of people these seem normal these days, but to me, they're not really how challenging activities are meant to be, and a lot of the fun aspects of a game are sucked out by them. As a result, more challenging cooperative content tends to come with a dramatic decrease in agency, and then all these various adaptations make it not as challenging.
I think what's actually happening is a lot of people want content that is flagged as difficult, so that they can clear it and point to themselves and say "I have cleared this difficult content". Which is not the same thing. That's why they get very angry at, say, off-meta play, because it affects their ability to clear the most difficult content, and why they don't seek out difficulty where it's available, because there's no cool achievement to wave afterwards. It gets extra bad when people start using clears or parsers against each other, since that just reinforces the behavior.
I have seen similar things around the Necromancer title. It seems people just want it for bragging rights, not as a fun challenge.
