Agree with you that having duplicate tests in suites is error prone.
IIUC, cases in a suite is determined at build time, as well as command options to run cases. This implies hugepage availability needs to be detected at build time if we want to run only suitable cases in suite in an environment. It could be something we don't want. I'll trim fast-tests in next version to remove duplicated cases.
