If you have a "command to set something up", if calling that command is not an idempotent operation then handling it in a declarative script becomes more difficult. You end up writing "if some file (generated as a side effect of that program) is not present, then run command, otherwise do nothing" instead of "ensure that some configuration file is in place with a well-defined content". While I think any tool that simplifies "getting started" is great, I think this may turn all too quickly into a "mean wizard" thing that does some black magic behind the scenes and that it becomes basically impossible to setup Mesos *without* the wizard.
