I guess we could introduce some sort of `xarray` specific formatting mini-language to solve that? For example:
- `f""{arr:r}""`: print the object's `repr` (the default)
- `f""{arr:b}""`: print the array backend's `repr` (only for `DataArray` / `Variable`)","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1316549018

Interesting idea. I was thinking just adding `format_spec` to `formatting.array_repr` so the repr can handle `__format__` as well should be enough. It seemed much more involved though.

Anyway that's for another PR. I think this PR is ready now, I think it should handle the main request in #5976 without being so intrusive in other cases.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1316549018

I believe this should be the same behavior as previously now with the extra possibility to format scalar arrays:

import pandas as pd
import xarray as xr

s = pd.Series(
    range(4),
    index=pd.MultiIndex.from_product([list(""ab""), list(""cd"")]),
)

da = xr.DataArray.from_series(s, sparse=True)

print(f""Error: {da} is sparse"")
Error: <xarray.DataArray (level_0: 2, level_1: 2)>

  * level_0  (level_0) object 'a' 'b'
  * level_1  (level_1) object 'c' 'd' is sparse

# Handle format_spec:
da = xr.DataArray([1, 2, 3])

print(f'{da[0]}')
<xarray.DataArray ()>
array(1)

print(f'{da[0]:d}')

print(f'{da[0]:f}')

Should it by default just use the repr instead? But it won't feel very consistent once string formatting are used though.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1316549018
