We generally don't surface our devDependencies to consumers. On all major changes we tend to offer brief but useful guidance on how to overcome the potential impact of these changes.
For example:

Removed `sass` and `ember-cli-sass` dependencies. Consumers using `sass` in their projects should make sure it's added as a direct dependency to their project.
