No provision to group API's and then $ref it to reference it in other file

In our application, we have apis divided among various modules.

As per swagger-spec, It becomes very difficult to have only one swagger file (api-docs) for all the modules considering the number of apis and also number of teams working on various modules.

So I started using $ref (purpose: same folder reference) and third party swagger parsers to dereference it. But I still cannot figure out a way in swagger to group apis with one $ref.
So that I can assign all apis for a particular module to a team and then just $ref in api-docs that can be dereferenced lately to get complete single api-docs file

Eg:

//something like that
{
    'pet' : '$ref': './pet.json',
    'user' :'$ref': './user.json'
}

Which when dereferenced, will change to

{
    '/pet' : {},
    '/pet/{name}' : {},
    'change/pet' : {},
    '/user': {},
    '/user/data': {}
}

Any help would be appreciated.

Issue で提案されているグループ化された $ref 構造と OpenAPI の参照ルールから始め、次に、その要求に仕様の変更が必要なのか、それとも外部デリファレンスだけでよいのかを判断します。完了の条件は、maintainers が承認した解決策と、文書化された動作です。Issue には実装ファイルやテストの指定はありません。
