Xarray knows to drop the dtype encoding after an arithmetic operation. How does that work? To me .chunk feel like a similar case: an operation that invalidates any existing encoding.

To be honest, the existing convention is quite adhoc, just based on what seemed most appropriate at the time.

https://github.com/pydata/xarray/issues/1614 is most comprehensive description of the current state of things.

We were considering saying that attrs and encoding should always use the same rules, but perhaps we should be more aggressive about dropping encoding.
