It was a giant mistake to keep 'classic' (umnaintained, unpatched) yarn around. Switched to pnpm in part due to that reason.

It's not exactly unmaintained (we merged a couple of security patches in the past years), I agree that we should have do something about it.

We'll be correcting this situation starting from the 6.x release, which we expect somewhere in August.
