Hollow Knight is a pretty great game, that overstays it's welcome and the last bosses (that I played.. haven't faced all of them after ~50hrs and quit the game after reaching 1 ending) are some bullet hell shit. I wouldn't categorize it as a "soulslike", it's a pretty straightforward Metroidvania and if you have trouble with the super precision platforming like I do then I think Ori 1 is a better fit for you as you can power up your skills/jumps farther than the game ever requires you to perform.
I'm inclined to agree with you on not including Hollow Knight as a Souls-like. It's why I didn't initially include it but then saw other people were including it so thought I'd mention I have played it but can't categorize it. I think people include it due to the way it handles bosses. You learn boss patterns and you get better at bosses while doing very little damage to them per attack. And it's unforgiving of even small technical mistakes on your part as the player.
I played through Ori and it was very demanding for me from a pure environmental platforming point of view. But you're right about Hollow Knight being impossibly demanding for me in platforming when dealing with bosses.
