'serviceProvidedInRoot'=false not working?

[sdwske]

I am working with lazy loaded modules in angular (user, manager and admin) and need generated GQL services to not be provided in root, but codegen.ts property serviceProvidedInRoot set to false does nothing in regards to:

  @Injectable({
    providedIn: 'root'
  })

...and 'root' is still present.
I want them to not be provided anywhere and do it by hand in lazy modules in:

@NgModule({ providers: [ GeneratedGQL ] }}

Given:

"@graphql-codegen/cli": "^2.13.12",
"@graphql-codegen/typescript": "^2.8.2",
"@graphql-codegen/typescript-apollo-angular": "^3.5.6",
"@graphql-codegen/typescript-operations": "^2.5.7",

I am running simple package.json script with pnpm:

"graphql": "graphql-codegen"

Can somebody reproduce and confirm this issue?

Or maybe i misunderstood this configuration feature?

P.S: serviceProvidedIn doesn't seem to work either.
