No ways to do an alias of an exported type inside a namespace

TypeScript Version: 3.9.7

Search Terms:
export type alias namespace

Code
With import type, in case of long namespaces encapsulation, there's no way to do an alias of the namespaces.
We are forced to alias the final types / interfaces

file types.ts

type A = {}
type B = {}
type C = {}

export type {
    A,
    B,
    C
};

file namespace1.ts

import type * as namespace1 from 'types';

export type {namespace1}

file namespace2.ts

import type * as namespace2 from 'namespace1';

export type {namespace2}

file finalUsage.ts

import type {namespace2} from 'namespace2';

type A = namespace2.namespace1.A; // this is working
namespace aliasNamespaces2 {
   export import namespace1 = namespace2.namespace1; // fails with message 'An import alias cannot reference a declaration that was imported using 'import type'. '
}

Expected behavior:
we need a way to make a shortcut of namespaces2.namespace1

Actual behavior:
Cannot do it: we are forced to aliasthe final types namespaces2.namespace1.A

まず、報告された TypeScript 3.9.7 のセットアップで、サンプルファイル types.ts、namespace1.ts、namespace2.ts、finalUsage.ts の動作を再現します。import type aliases と namespace references の処理を追跡し、そのうえで、現在の import-type error を発生させずに namespace2.namespace1 を短縮する、サポートされる方法を定義してテストします。
