Well, yes, if you take that literally.
As aparently 'condition' checks in routers do. ;)
With my programmer mindset it should "expand" to False (0).
Router conditions literally test for the string '', '0' or 'false'.

Thanks for your time, Slavko. This is what i ended up using!!
Do you think usage of '!' in router conditions should trigger a warning?
