TemplateFactory type incompatible with setComponentTemplate type from @types/ember__component

[simonihmig]

With ember-cli-htmlbars 6.3.0 and latest version 4.0.22 of @types/ember__component, for this type of code...

import { hbs } from 'ember-cli-htmlbars';
import { setComponentTemplate } from '@ember/component';

export const Button = setComponentTemplate(
  hbs`
    <button>{{yield}}</button>`,
  templateOnly(),
);

I am getting this type error:

Argument of type 'import("/[...]/node_modules/ember-cli-htmlbars/lib/index").TemplateFactory' is not assignable to parameter of type 'TemplateFactory'.
  Property '__htmlbars_inline_precompile_template_factory' is missing in type 'import("/[...]/node_modules/ember-cli-htmlbars/lib/index").TemplateFactory' but required in type 'TemplateFactory'.ts(2345)
index.d.ts(14, 5): '__htmlbars_inline_precompile_template_factory' is declared here.

@types/ember__component is still defining TemplateFactory like this:

interface TemplateFactory {
    __htmlbars_inline_precompile_template_factory: any;
}

But #764 removed that __htmlbars_inline_precompile_template_factory property (used as a way of type branding I guess?), so I am indeed wondering how this is supposed to work now? Maybe just working with Ember's native types?

It should work with Ember's native types (I believe that’s part of why that change is shaped the way it is), but it may also make sense to back-port a compatibility fix to the DT types for it.
