Am I the only one that hates the decision to no longer support corepack?

pnpm 12 supports corepack (or better phrased - corepack supports pnpm 12).

they just don't recommend it.

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.

First I'm hearing of it, and it does dampen my enthusiasm for v12 a bit.
