sub-query is, the subquery itself will be AQE-ed, which can lead to performance
regressions due to missed opportunity of sub-query reuse. (was: Currently
there are unsupported queries by AQE. But if the main query is unsupported
while the sub-query is, the subquery itself will be AQE-ed, which can lead to
performance regressions due to missed opportunity of sub-query reuse.)
