I thought @aurghs did respond to this issue and forgot about it.

What has happened is not that `lock` (and `group` for the matter) disappeared altogether, but it has been moved to be a backend specific keyword argument. As far as I can see most internal backends still support it as before: `cfgrib`, `netcdf4`, `pseudonetcdf`, `pynio` and `scipy`.

The main difference is that `lock` was silently ignored by backend that don't support it like `zarr` and `pydap`.

The solution is to in fact only advertise the deprecation for those backends in my opinion as the functionality is legit for most of the backends.

Sorry again for seeing this so late.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,840258082
