Enforce that only deeper "nested" packages can be imported but no siblings

[timofurrer]

Is it somehow possible to enforce that only deeper nested packages can be imported but no siblings (of any level), for example:

internal/commands/
├── project/
│   ├── main.go              ← Can import view/, create/, publish/ and everything in internal/ (but nothing else in internal/commands/)
│   ├── view/
│   │   └── list.go          ← Cannot import ../create/ or ../../release/create 
│   ├── create/
│   │   └── main.go          ← Cannot import ../view/ or ../publish/catalog
│   └── publish/
│       ├── main.go          ← Cannot import ../view/ or ../../release/create
│       └── catalog/
│           └── sync.go      ← Cannot import any other subpackages
├── release/
│   ├── main.go              ← Can import create/, publish/
│   ├── create/
│   │   └── main.go          ← Cannot import ../../project/publish/catalog
│   └── publish/
│       └── main.go          ← Cannot import ../create/ or ../../project/view
