This is very related to #23132 (but not the same).

Currently Span Length is limited to just under Int32.MaxValue.

This is problematic when working on relatively large data, as we have to resort to working with raw pointers and unmanaged memory allocation to work with contiguous arrays of 2G+ elements.

To give a concrete example, from .NET I can't simply give TensorFlow 800_000 64x64 1-channel (channel==byte) images as a contiguous array.
