According to these:
Writing .info files (Drupal 7.x)
#1346158: Decide on coding standard for capitalization of module names [policy, no patch]
Proper Case should be used. So, "Drupal Core" instead of "Drupal core".
Some of the modules have been converted via:
#1430452: Use Proper Name Case for core modules
but there are a couple to still tackle:
config/config.info.yml:name: 'Configuration manager'
rest/rest.info.yml:name: 'RESTful web services'
along with the places in the code that refer to these modules as projects, i.e.
"Use the RESTful Web Services configuration page"
rather than
"You can configure RESTful web services using the Drupal UI"
