LGTM. This is a nice cleanup.

I suspect you are procrastinating from something.

Trying to reland this, RemoteFileSystemExtensionApiTest is fixed.

kinaba,
Could you review the test fix?

I'm very worried if this patch landed before the branch cut or not. If it didn't
land before the branch cut, we should revert this. As mentioned elsewhere, after
the branch cut, Drive code will enter the "no refactoring" period.
