SERVER-121092 disallowed checking the current status of the viewless timeseries feature flag in FCV upgrade/downgrade suites, since it can change at any time so those checks are racy.
Then SERVER-121471 enabled viewless timeseries in FCV upgrade/downgrade suites.
Soon afterwards SERVER-123176 checks if the current status of the viewless timeseries feature flag is disabled to skips some tests.
This is hitting the check added by SERVER-121092 - some tests consistently fail because of this (e.g. buildscripts/resmoke.py run --suite=fcv_upgrade_downgrade_replica_sets_jscore_passthrough --runAllFeatureFlagTests jstests/core/timeseries/ddl/timeseries_clustered_index_options_legacy.js) so we should make sure the checks in SERVER-123176 also skip the test if the viewless timeseries flag is not stable.
