nodejs stopped bundling corepack since node 25, maybe you're referring to that?
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.
Same here. Corepack was fine and there is already too much churn
It is node.js core that decided to drop corepack, now both yarn and pnpm are build own version of that.
I migrated a Node 24 repo to pnpm 12 and it works absolutely fine with corepack out of the box.
First I'm hearing of it, and it does dampen my enthusiasm for v12 a bit.
