In MDL-71546 a new user tour was added to core, and set as "shipped" one. This was applied to both 311_STABLE and master (because we were in a parallel development period at the time being).

This issue is about to decide when that user tour will be removed (they use to be short-lived).

I'm setting this as 4.0 blocker so we ensure it's visited before then. The decided version can be the very same 4.0 and also any other future one.
