I don´t get the design choice for Glimmer components:

  export default class CounterComponent extends Component {
    <template>
      <p>0</p>

      <button type="button">+1</button>
      <button type="button">-1</button>
    </template>
  }

This is obviously not valid JS. If they already had to create a DSL for components, why not embrace it fully and introduce a different keyword instead?

    export default component CounterComponent < Component {
        <template>
            <p>0</p>

            <button type="button">+1</button>
            <button type="button">-1</button>
        </template>
    }

JSX class components, even though not technically valid JS (render method returns HTML-like syntax), resemble a JS class much more as it requires methods to declare the template and handle component lifetime.
