The other downside of Features in Drupal is that if we export something as a Feature (say a View) and then our site builders tweak and change that View for our clients and then we update some core element of that View and re-export the Feature, that re-export will overwrite any custom changes that were made to that View, thereby trashing any of the custom changes. This is a real problem with Features to which I'm surprised there has not yet been a good solution.

Same problem as other frameworks. You need to know the rules. If you use rails, and the designer changes the CSS without committing the change to git, then next code push will erase his change.
