For now we've monkey-patched it to our usecase:

LOL, that's a cool hack

That gives us the benefit of creating "local datasets" (confined to the scope of the project, do not appear in

Datasets

tabs, but appear as normal tasks within the project)

So what would be a "perfect" solution here?
I think I'm missing the point on why it became an issue in the first place.
Notice that in new versions Dataset will be registered on the Tasks that use them (they are already there in the Info Tab, and will be part of the configuration as well, so that you can override them if you wish when running remotely).
The second point is to better highlight the "creating Task" of a dataset, so that the preprocessing code is more visible in the Dataset UI.
What else am I missing ?
