In regards to today\u2019s meeting, I wonder if base filters from <https://github.com/apache/incubator-superset/pull/10946> wouldn\u2019t solve the data access problem by introducing a `1 = 0` base filter for all and then adding regular filters for roles that should be allowed to access the data.? If so, the remaining work would just require adding security constructs for making sure that the user has access to the dashboard metadata (the same roles could be used for this as the RLS regular filters).
