• Collection_validator_feature_compatibility_version.js - We should investigate updating this test to additionally test that we will not allow creation of collection validators using new query features when the FCV is in downgrading, not just when the FCV is fully downgraded to last-continuous or last-lts.
• View_definition_feature_compatibility_version.js - We should investigate updating this test to additionally test that we will not allow creation of a view using new aggregation features when the when the FCV is in downgrading, not just when the FCV is fully downgraded to last-continuous or last-lts.
