Lot of hot takes. I've not played Sekiro yet because money, but I will say this: Anyone who thinks From games are hard is wrong and fell for a marketing tactic.
"Oh yeah but people are struggling with Sekiro"
Yeah, yeah. As a series veteran I saw the same thing when there was this buzz about this hot new weirdo game called Demon's Souls. I saw the same thing when Dark Souls 1 came out, then Dark Souls 2, then Bloodborne, not so much with Dark Souls 3, mainly because (I suspect at least) people had wisened up to the fact that nobody cares if you can beat dark souls because it's not as hard as it's made out to be. Did we all forget the rest of the series?
When I first played Demon's Souls it took me around 20 or 30 tries to even get close to beating the Manflayers. But now that I know the game to a decent extent I can hammer it in one, maybe two. When you learn the game it gets easier. When I played Dark Souls for the first time I was getting butchered by Queelag for a couple days, today it's rare for me to even get my heart rate up for the Queelag fight, nail it first time every time.
Give it a month or two, people will figure out what makes Sekiro tick (as in, the reason it's not Dark Souls 4 or Bloodborne 2) and it won't seem as hard. Trust me, I've seen this happen with this exact same dev enough times to know.
It's not that the game is hard, it's that it's not for everyone. I don't mean "not for everyone" as in it's just too hard for some people, I mean it's not for everyone in the same way black coffee is not for everyone. If you don't enjoy feeling like a game is putting you under pressure and making demands of you, then you're not going to have fun. It's hard to say this without sounding like an elitist, but there's a pretty good reason why people still want Bloodborne 2, because you don't feel as under pressure and the game is more forgiving of mistakes. It's a different game that appeals to a different audience.
Really that's it, I can't remember who said it, but I do remember them being wrong about a lot of things in From games but there's one thing they were dead on correct about "Dark Souls kills you and then gives you a shield, Bloodborne kills you and then gives you a sword and a gun." Different mode of play, different tools, different audience. Get me?
Maybe the problem is that a lot of people just don't enjoy the game as it is? I mean, say you want an easy mode. All your damage output is doubled, all enemy damage is halved. Would you really, truly enjoy the game more? Would that really help people with disabilities that interrupt their enjoyment of the game? (I know there's more to difficulty than that, but it's damn rare for devs to do any more than that.) You'd still die for trying to play outside the "rules" of the game, just maybe not as frequently still a significant amount.
And I've been saying this since 2011, "If you die in Dark Souls, it's 90% of the time because you weren't paying attention. 10% of the time because the game threw actual unfair bullshit at you." I count Giantdads as unfair bullshit by the way. Still, THE LEGEND NEVER DIES.
While I'm not quite against entirely an easy mode in Souls, I simply don't think it's the solution to accessibility. If you want accessibility you're much better served asking for colorblind modes, remapping controls as an industry standard, minimum 60fps (yes a higher framerate can be a real help to people with certain disabilities in games) UI size configuration, hold options for repeated button presses. Eliminate the actual barriers to entry.
Sadly there are some aspects of some disabilities that will completely eradicate the ability to play most games and you can't always design to compensate for those, however the features I listed above are a big step toward helping most people who need it.
