Nothing "prevents" you from using a "new" value. There are 20 ambiguous `=spinner`, and 1 `=spinning_dish` (and 1 `=spinningdish` and `=spinningbowl` typo). We can think about whether to use `=spinner` + `spinner=*`, something like `spinner=*` (or spinner:*=*`), or `playground=*` directly. Before that, it may be more important to clarify what are they actually called. Both "wheel" and "disk" may be confused with merry-go-rounds.

Use `description=` and `description:en=`.

It's a wiki, not "Wikipedia".
