Requesting review of Ember test selectors (data-test) excerpt from the testing guide

I am interested to know how I can request a change of these excerpts from the Testing guides, and whom I can reach for the following concerns. Kindly guide.

### excerpt
https://github.com/ember-learn/guides-source/blob/1ae44e82e19f641af4156f8c48b09b3172641c6b/guides/release/testing/testing-tools.md?plain=1#L92
> Class names and DOM structure change over time—for the better—by you, your team, and addon developers. If you rely on CSS classes, your tests will break and need a significant rewrite

### concern
When DOM changes are unavoidable, it is natural that the `data-test` selectors will **also** need to be moved, and refactored. How does using `data-test` selectors provide any perceivable/measurable value?

> If you rely on CSS classes, your tests will break and need a significant rewrite.

### concern
Don’t we want this? Classes are part of the user experience, so tests **should break** if they change. If not, then this concern is also applicable to `data-test` selectors. That is, when you change the DOM you also need to move/change `data-test` selectors without which the tests will break in a similar fashion and will need rewrite.

In that case, `data-test` selector becomes useful exactly in this case when you have an element
- that can change the type (span ➞ div ➞ li, etc),
- can change the class,
- but still, needs to play the same role? This is not common and is sometimes unrealistic.
