We had built a series of curated workspaces that gave our end users a set of carefully selected projects to be able to interrogate the data. They restricted the projects to simple sets of data making it easy for our users and also restricted them having access to the full set of dimensions which we didn't want them to have.#
We did and do not want our non analyst community to be able to create their own workspaces but rather use the ones we had created for them. They were pre-built, simple to use and controlled.
What you have done now is open up the full workspace to everyone. We wouldn't have dreamed of giving our non-analysts access to Ad-Hoc analysis yet we are now giving them access to create uncurated projects in the more powerful workspace with the full range of dimensions.
