Flat data for the tree

I want to have flat list of objects, more like a relational database, rather than real tree. But it has all the info for the tree:

const treeDataList = [
  {
    key: '0-0',
    title: 'parent 1',
    children: ['0-0-0', '0-0-1'],
  },
  {
    key: '0-0-0',
    title: 'parent 1-1',
    children: ['0-0-0-0'],
  },
  { key: '0-0-0-0', title: 'parent 1-1-0' },
  {
    key: '0-0-1',
    title: 'parent 1-2',
    children: [
      '0-0-1-0',
      '0-0-1-1',
      '0-0-1-2',
      '0-0-1-3',
      '0-0-1-4',
      '0-0-1-5',
      '0-0-1-6',
      '0-0-1-7',
      '0-0-1-8',
      '0-0-1-9',
    ],
  },
  { key: '0-0-1-0', title: 'parent 1-2-0' },
  { key: '0-0-1-1', title: 'parent 1-2-1' },
  { key: '0-0-1-2', title: 'parent 1-2-2' },
  { key: '0-0-1-3', title: 'parent 1-2-3' },
  { key: '0-0-1-4', title: 'parent 1-2-4' },
  { key: '0-0-1-5', title: 'parent 1-2-5' },
  { key: '0-0-1-6', title: 'parent 1-2-6' },
  { key: '0-0-1-7', title: 'parent 1-2-7' },
  { key: '0-0-1-8', title: 'parent 1-2-8' },
  { key: '0-0-1-9', title: 'parent 1-2-9' },
]

Does rc-tree support such a flat shape? Ofc, I may make some additional layer myself, so original data will stay flat, but for the tree I'll have this additional layer which will be actual tree. But I'm wondering if it's already supported, because, well... It looks like a pretty much common case.

If it's not supported, what do you think about this idea?

Start by reviewing rc-tree's current data-shape API and usage examples to determine whether a flat list is accepted directly. Define the expected flat-data behavior and conversion boundaries, then document or test the conclusion; the issue is done when supported input or a clear implementation proposal is established.
