Overview

Several query stats feature flag checks use .isEnabled() instead of .isEnabledUseLastLTSFCVWhenUninitialized(). These should be updated for consistency and correctness, as isEnabledUseLastLTSFCVWhenUninitialized is the preferred method for checking query stats feature flags.

Locations to Update

• src/mongo/s/commands/query_cmd/cluster_count_cmd.h:150 — gFeatureFlagQueryStatsCountDistinct.isEnabled(...)
• src/mongo/db/commands/query_cmd/distinct.cpp:164 — gFeatureFlagQueryStatsCountDistinct.isEnabled(...)
• src/mongo/s/commands/query_cmd/cluster_distinct_cmd.cpp:163 — gFeatureFlagQueryStatsCountDistinct.isEnabled(...)
• src/mongo/db/exec/agg/query_stats_stage.cpp:205 — gFeatureFlagQueryStatsMetricsSubsections.isEnabled()
• src/mongo/db/query/query_stats/query_stats.cpp:409 — gFeatureFlagQueryStatsForInternalClients.isEnabled()
