/**
* This is provisional code while we investigate approaches how to associate custom generation plans
* with a model. We've tried <code>CustomGenerationModuleFacet</code> which is not quite satisfying,
* as we need to give Language Designer control over plan activation, and less (no) burden for Language Practitioner
* to pick a plan for his model.
*
* XXX It's indeed a hack to return model reference here, but it's the only way to move forward quickly.
* I can't afford to spend time now to build a facet mechanism for devkits, or to introduce GenerationPlanIdentity
* to reference deployed plans which could be kept here (and supplied from extension point or any other similar mechanism).
* At the end of the day, there'd be some compiled representation of the plan, we we can identify and assign here (if we stick
* to plans at devkits approach, which is not yet 100% sure thing).
