Their benchmarks[0] report that a clean install with lockfile is about 3x times faster (7s -> 2.2s) and a no-op install is about 29x times faster (517ms -> 18ms)
Is "pnpm installs the other package managers" what you're talking about, or something else? That doesn't quite read like removing corepack support to me, though I might be missing something obvious.
I was also bothered by this. I don't care if you use LLMs to write most or all of your code, but at least have the courtesy of actually writing your blog posts & readmes, to demonstrate that you at least understand what the LLM generated for you.

they just don't recommend it.
nodejs stopped bundling corepack since node 25, maybe you're referring to that?
