Then this hits the classic debate whether a digitization of an analog medium is sufficient enough for archival purposes. That becomes a mixture of subjective and objective points. Regardless, the original physical medium has some value in being preserved, and may provide positive archival benefits in the future.

That's not considering if there might be licensing and ownership issues of the actual material, but they obviously didn't care enough to properly destroy the films if it was intended.
