### Describe the bug

libraries like axios-mock-adapter define an adapter but in same cases need to access to original adapter.

It was working correctly before as the adapter was always a function.
Now it can be an array of string

Only the method getAdapter() in adapters/adapter.js can allow access to original adapters (xhr and http)
But this method is not exported a all at top level.

Can you export it ?
