In addition to the top-level API compatibility layer, we are also seeing that some applications are interacting with the Array class constructor directly. For example, see this from Dask.

z = zarr.Array(url, read_only=True, path=component, **kwargs)

But our current constructor doesn't support this.

To be honest, I've been assuming no one was using Array.__init__ but that seems to have been a mistake.

Thanks @will-moore for reporting this (#1884 (comment)).
