Ref: #378997 (closed)
It replaces the usage of default_values_for on ProjectFeature model with a native Rails feature because that gem is unmaintained and it's blocking us from upgrading to Rails 7.
Used a similar technique implemented in !103787 (merged) to deal with existing records and making sure we set correctly their default value.
This checklist encourages us to confirm any changes have been analyzed to reduce risks in quality, performance, reliability, security, and maintainability.
