2120030667,PR_kwDOAMm_X85mGm4g,8712,Only use CopyOnWriteArray wrapper on BackendArrays,35968931,open,0,,,6,2024-02-06T06:05:53Z,2024-02-07T17:09:56Z,,MEMBER,,0,pydata/xarray/pulls/8712,"This makes sure we only use the `CopyOnWriteArray` wrapper on arrays that have been explicitly marked to be lazily-loaded (through being subclasses of `BackendArray`). Without this change we are implicitly assuming that any array type obtained through the BackendEntrypoint system should be treated as if it points to an on-disk array.

Motivated by https://github.com/pydata/xarray/issues/8699, which is a counterexample to that assumption.
