Hi Adam, In my opinion it is a bug. My thinking is this, if there's no Catalyst work to do then the performance penalty for using Catalyst should be negligible. The VTK grid should only be generated if there's Catalyst work to do (this will usually be quite fast but certainly may not be negligible) and if there aren't any outputs (e.g. images, data extracts or to Catalyst Live via a connected client) then RequestDataDescription() should return that there's no work to do so that no cycles are wasted generating the VTK object. If you don't mind wasting cycles, I can always have you compute some bitcoins for me instead :)
Additionally, all of this should be automated (and can be) such that it just works for users without having to modify the Python scripts for something as simple as this.
