While that might have been unintentional at the time I don't think `resample` should have that option, so maybe we should just raise a warning like we do for `keep_attrs` and eventually remove both.

Does this do what you expect?
```python
In [2]: da.resample(time=""A-Dec"").mean(skipna=True)
Out[2]: 
<xarray.DataArray (time: 1, value: 1)>
array([[6.5]])
Coordinates:
  * value    (value) int64 0
  * time     (time) datetime64[ns] 2022-12-31

In [3]: da.resample(time=""A-Dec"").mean(skipna=False)
Out[3]: 
<xarray.DataArray (time: 1, value: 1)>
array([[nan]])
Coordinates:
  * value    (value) int64 0
  * time     (time) datetime64[ns] 2022-12-31
```

Edit: I don't think this is related to #6772, but I'll also have a look at what's wrong there","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1593589979
