Peers are not checked in workspace

[hyperknot]

I'm trying to understand the basics of workspace and peers.

I created the following minimum repro setup:

./package.json
---
{
  "private": true
}


---
./pnpm-workspace.yaml
---
packages:
  - 'packages/*'
  - 'web'

autoInstallPeers: false
strictPeerDependencies: true


---
./web/package.json
---
{
  "name": "@myproject/web",
  "private": true,
  "type": "module",
  "dependencies": {
    "@myproject/shared": "workspace:*"
  }
}


---
./packages/shared/package.json
---
{
  "name": "@myproject/shared",
  "private": true,
  "type": "module",
  "peerDependencies": {
    "drizzle-orm": "^0.44.2"
  },
  "dependencies": {
    "lodash": "^4.17.21"
  }
}

The key is the

  "peerDependencies": {
    "drizzle-orm": "^0.44.2"
  },

part in shared/package.json

In my understanding, not having this dependency in the web package should throw an error. But it doesn't, not even if I add strictPeerDependencies: true.

Why is this the case? I've tried everything, but cannot figure this out. pnpm list -r doesn't list it either.

pnpm list -r
Legend: production dependency, optional only, dev only

@myproject/shared .../pnpm_peers/packages/shared (PRIVATE)

dependencies:
lodash 4.17.21

@myproject/web .../pnpm_peers/web (PRIVATE)

dependencies:
@myproject/shared link:../packages/shared
