I don't have the full overview there.

@mathause indeed we've made a lot of progress.  A few remaining missing things that come to mind (there could be others) are:
- Support for missing values in arrays of cftime objects (I should probably create an issue for this)
- Possible PeriodIndex-like functionality with cftime objects (#2481)
- [`coarsen`](https://github.com/pydata/xarray/blob/8a1a8a1f13462440543581cd12fb96f22f0748bc/xarray/core/common.py#L593-L647) (coming in the next version of xarray) still needs to be updated to work with cftime coordinates (waiting on #2668 before starting on that) 

Out of those three, `coarsen` is probably the highest priority on my list at the moment (the other two would require some more careful thought).  ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,407864596

```
//anaconda/envs/xarray-dev-37/bin/ipython:2: SerializationWarning: Unable to decode time axis into full numpy.datetime64 objects, continuing using dummy cftime.datetime objects instead, reason: dates out of range
```
The rationale for keeping this warning is that for standard calendars (like `'proleptic_gregorian'`) we use pandas/NumPy dates by default; therefore falling back to using cftime in this circumstance is a deviation from the default behavior, which might come as a surprise to some users.  

I wonder if it might make sense to offer an [option](http://xarray.pydata.org/en/stable/generated/xarray.set_options.html) in xarray to always decode times to cftime dates, even for standard calendar dates between years 1678 and 2262 (which, if set, could also silence this warning); this would be another possible solution for #1263.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,407864596
