MUL has already been released on Test Wikidata and on Beta Wikidata, but for testing we need to complete:
* T355059
* T356200
* T356201
* T345883
* T135871
For testing we must also switch MUL to a limited feature on Beta which means that:
* `mul` only visible via Babels
* no on-boarding element
* updated feature flag for limited release (see T316767)
**Phased release**
| Milestone | Phase | Where | Feature flag (see T316767) | Task
| ----- | ----- | ----- | ----- | -----
| 1.0 | 1. Test release | test.wikidata.org | Full feature (`mul` visible for everyone, on-boarding element) | THIS TASK
| 1.0 | 1. Test release | beta.wikidata.org | Limited feature (`mul` only visible via Babels, no on-boarding element) | THIS TASK
