While I understand what you're talking about, I would argue it's bad metaprogression that you dislike. I liked Rogue Legacy when I first played, but didn't enjoy the second one even though it's essentially the same. Let me give you an example of good metaprogression: Dead Cells.
There's the metaprogression that allows you access to new areas and new mechanics, but that's fairly quick compared to the length of the rest of the progression, and I would argue it's not the sort of thing you're complaining about.
What could be similar is the way you unlock equipment, although you don't become stronger with each run, you unlock more weapons. This gives you variety, but the vast majority of the progression happens in your head. If you have enough hours in Dead Cells and think the metaprogression is what made you so good at the game that you couldn't finish one level when you started and now you play for hours, do me a favor and start a new save. After being on the second cell I bought the game for a different platform, on my first run I got to the first cell.
Which brings me to the second metaprogression in the game, cells. They make the game harder, not easier, and it's the way to progress, you have to purposefully make the game harder to progress. IMO this is how metaprogression is supposed to be done, you need to be better, and when you think you're good enough to beat the game it lets you know "you've only just started".
I guess If I were an article snippet I would also like an explanation
