1709181628 PR_kwDOAMm_X85l4Aq8 8697 closed 0 add open_datatree to xarray 479480 Draft: I'd like to open this up and start a discussion on a couple of things. Here is a first stab at adding open_datatree to the backend of xarray. 1. ~~I'm not sure which tests to migrate/write with this change. The only datatree tests that have open_datatree are the ones in tests/test_io.py. While those (and all of the datatree tests) run and pass, they are still located in _datatree, and they don't seem to fit in the test_backends.py. I do see that Tom did a good job of naming the tests so that they would fit with the existing tests in many places.~~ Migrated tests over into xarray/tests/datatree once approved and merged can be added into the existing tests where appropriate [(from Tom)](https://github.com/pydata/xarray/pull/8697#pullrequestreview-1860425936). 2. I was able to open datatrees with each of the engines, netcdf4, h5netcdf and zarr. 3. I haven't moved any documentation. I remember hearing that we could add it and mark it as experimental? Is that the correct way forward?
