The vHost examples on the Wiki used the feature-mask of 0xFF. I think that is how it got propagated. In 16.09 when I did the CLI documentation for the vHost, I expanded what the bits meant and used feature-mask 0x40400000 as the example. I will gladly add an additional comment indicating that the recommended use is to leave blank if this was intended to be debug.
