AFAICT, the type checking in the _validate_datatypes_for_zarr_append is simply too strict, and relaxing it seems to work fine. But this is my first time digging into the xarray source code, so please let me know if this issue is more complex.

Thanks for the contribution @amatsukawa ! Happy to have you as a contributor.

Looks good to me; though I don't know this part of the code well at all, so I'll let someone have a look before we merge.

Do you want to add a whatsnew comment with attribution?

Thanks @max-sixty, I made a small update to the error message.
I had added a line to doc/whats-new.rst in 2e91693 is that what you were referring to?

Perfect @amatsukawa !

Any comments from someone who knows the code? Otherwise tests look good enough to merge...

The tests look sufficient to me... but then again I haven't looked at the zarr code either.
