Resuable features and Composer workflow

Since Composer is now the dependency manager for Drupal, I would like to get some advise how to reuse features.

For example, I have created a image gallery (content type, some fields and a view). For the display I have installed Display Suite (DS) so there is an extra module needed for this feature.

In the old days I would have copied the feature to a new site and would run "drush en " and all the dependencies were downloaded and installed automatically.

In the D8 Composer world, I need to run "composer require drupal/ds" and after that I can enable the feature.

Her is my question:
Is there a way that features can see or advise to update the composer.json so dependencies wil get installed automatically?

Thanks in advance
