Currently, there is a special test run in Evergreen for "I18n fallbacks enabled". It appears that the original authors did this because I18n fallbacks is a global setting. It would be much better to handle this setting using RSpec mocks instead, and unify the test runs.Currently, there is a special test run in Evergreen for "I18n fallbacks enabled".

I would suggest the following approach:

• Write a test helper that mocks I18n fallbacks being enabled. This can be done as an `around` block in the test suite (enable, yield, disable).
• Search the test code for "I18n", "localized", etc. to make a list of where localization features are used.
• For each feature, add a `content 'when I18n fallbacks enabled'` block.
• Remove the I18n fallbacks test run.
