    I wouldn't, probably. It's super old and not very fast because it has to consider stride and stuff.

    We intend to obsolete NativeSlice and advise against its usage. The primary driver behind this decision is that indexing with NativeSlice is slow. Instead, we suggest exploring alternative methods to extract portions of data using stride or aliasing tailored to the specific use case. For example, consider aliasing a NativeArray to get parts of its data, NativeArray.GetSubArray().
