Index scans are currently ineligible for Bonsai Plan Cache, so the corresponding JS test cases are disabled when Bonsai Plan Cache is enabled. Once index scans are supported, these testes should be re-enabled by removing the check for the Bonsai Plan Cache feature flag:

• jstests/core/query/plan_cache/plan_cache_clear.js
• jstests/core/query/plan_cache/plan_cache_sbe.js
• jstests/core/query/plan_cache/plan_cache_sbe_hinted.js

Other tests will require implementing fast path disablement because the entire test uses indexes. The above three tests provide examples for how to do this in a passthrough test. noPassthrough tests can directly set the query knob for internalCascadesOptimizerDisableFastPath to true.
