Current Behavior

Inside a component we have this code:

// ...
// omitted useless code
// ...

export interface ConfirmationService {
    confirm(): void;
}

@Component({
    tag: 'my-component',
    shadow: true,
})
export class MyComponent{
// ...
// omitted useless code
// ...

Everything is compiling and working correctly.
This works only with interface, exporting Classes or Functions throws an error.
Is this fine and we can do that, or it may lead to unexpected behaviour and problems with the bundling as documented?

Expected Behavior

As documented here https://stenciljs.com/docs/module-bundling#one-component-per-module I would expect the compiler to throw something like:

[ ERROR ]  src/components/my-component.tsx:4:1
        To allow efficient bundling, modules using @Component() can only have a single export which is the component
        class itself. Any other exports should be moved to a separate file. For further information check out:
        https://stenciljs.com/docs/module-bundling

  L4:  export interface ConfirmationService()
