[Modern] Best way to write platform-specific (ios, android, web) fragments?

I have the following fragment:

```graphql
info: graphql.experimental`
fragment Url_info on Url @argumentDefinitions(
web: { type: "Boolean!", defaultValue: false }
ios: { type: "Boolean!", defaultValue: false }
android: { type: "Boolean!", defaultValue: false }
) {
id
webUrl
appUrl: webUrl @include(if: $web)
appUrl: iosUrl @include(if: $ios)
appUrl: androidUrl @include(if: $android)
}
`,
```

This is okay, but it becomes very cumbersome to duplicate @argumentDefinitions and @arguments over and over for all parent containers and pass down variables all the way down to platform-specific components.

I tried using `index.ios.js` and `index.android.js`, but it does not work because fragments in different files will share the same fragment unique id.

Is there any convenient way for this?
