When exporting configuration for a node type with fields with Drupal 8.2, I noticed that
translatable: true is set in
translatable: false is set in
my_field is of type
Text (plain), i.e.
string in the YAML file.
What does it mean for a field to be translatable, while the instance is not? It doesn't make sense to me.
Disclaimer: I'm not sure whether phrases like "field" and "field instance" are still applicable in Drupal 8, or whether that is just 7-speak.
