Just my two, out-of-context cents:

Robert Harris has gone on record as having said that Disney definitely knows what they’re doing with every single one of their products. For every home release that purists decry as inaccurate, there’s at least one archived print or scan far less fuddled with sitting in their vault for preservation reasons. So, yes, they do have versions of their animated closely that match the original releases more closely than what’s available to us.

Applying that logic, I fully expect them to restore the OT at some point. What I don’t expect is us to see that until they feel the time is right - if ever.
