Review comment:
Ah, the removal of segments from the broker could also mean that a
datasource is no longer global/joinable and so also could require a rebuild, so
i'm not sure we can remove it anymore without rethinking/reworking some other
stuff. Since there were multiple places that we add to
`dataSourcesNeedingRebuild`, but only one place we add to `tables`, it seemed
less room for error to do the filtering here in the only place we populate it.
