"issue pool application warning even if pool is empty" change

Hello, What was the motivation for the "issue pool application warning even if pool is empty" change [1]? This didn't occur to me what I saw the PR, but it basically makes it impossible to create a pool without HEALTH_WARN popping up. The reason is that pool creation and pool application enablement are separate monitor commands: there is no way to create a pool and enable an application on a pool atomically. And this is why this health check has always been limited to in-use pools (also pointed out by Greg when it was being introduced [2]).
