What problem does this feature solve?

most of series support to set cursor style but map,Can map support custom cursor style?
like this:

series:[{
  type: 'map',
  data: [
    {item:'aa', itemStyle:{cursor:'move'}},
    {item:'bb', itemStyle:{cursor:'pointer'}},
    {item:'bb', itemStyle:{cursor:'none'}},
  ]
}]

What does the proposed API look like?
