Define module as feature

Question

Creating a module with Drupal Composer asks me:

Define module as feature (yes/no)

What does it mean?

Answer 1

That option will add some code to the generated module to make it a Feature module - a module that provides some exportable configuration.

Answer 2

It just adds a file with the name of the feature bundle, and the feature bundle is nothing but a way to group features.

With this file your module will appear on the features list.
