Interesting. Do you think it's a feature that isn't used much? Or is it possible that inheritance isn't quite working as intended?

I think it works as intended, but maybe many of the summaries that already were relevant for subtypes = true had that set. The FlowSummaries test also reports that changing the logic only means that all the summaries applies to 44 extra callables (in all the libraries/frameworks included in the test) - so it is not that surprising that we don't see any changes in the alerts.
