```sh
npx ember-holy-futuristic-template-namespacing-batman-codemod ensure-template-only-has-backing-class
```
We would like to colocate templates but, when no backing class exists, colocated templates extend `templateOnly` instead of `Ember.Component`. Generating the backing class helps avoid any behavioral changes.
We can also run the `tagless-ember-components-codemod` to put the tags into the templates at which point we could convert these back to template-only components.
This reverts commit 20780a1eee.
* SECURITY: re-adds accidentally reverted commit:
03d26cd6: ensure embed_url contains valid http(s) uri
* when the merge commit e62a85cf was reverted, git chose the 2660c2e2 parent to land on
instead of the 03d26cd6 parent (which contains security fixes)
