> The s3guard markers audit -expected N command is meant to verify that the marker count is N, but
> * it isn't verified if the #of markers is 0, so you can't use it to assert that markers have been created
> * it doesn't work for tests where you expect a minimum number of markers.
> It's essentially setting a max #of markers
> Proposed: explicit -min, -max args to declare a specific range of values
