Can I exclude files only from root directory?

[pironmaurice]

I want to exclude a specific file from the deployement, but only in the root directory. According to this logic:

/composer.json -> shall not be deployed
/site/example/composer.json -> shall be deployed

Glob Patterns Tool

In the linked glob pattern testing tool this logic can be implemented, but it does not work in my tests. See here:

Glob Tool Test

Any ideas or is this actually a bug?
