I like the term for how effective it is at explaining something with some really simple shorthand, though I think it might be a bit overexposed and, like you said, used to describe games that aren't exactly that.
In Discord, you mentioned Iconoclasts as an example and I do think that one chafes up against the boundaries of the term. But generally, I feel like it's good shorthand to at least set the stage for what to expect.
All that said, I think this one fits the more strict definition of the term and definitely leverages earning new abilities to gain access to spots that were previously off limits. Exploring also rewards with more life, which is a nice bonus to earn. Not to bring Iconoclasts back up, but that one was not great about giving you compelling stuff to search for.
