Yes, also makes complete sense from a cultural perspective. If there is any sort of process involved in making a copy on new formats as they emerge, then you have to maintain a culture of people that are willing and able to execute the process. Far simpler to use a technology that is proven to work over several hundred years. Exhibit A: The Magna Carta [1]. With care, you can pick it up and read it, even today,

Automation won't hack it either. At the moment, the most complex machine that we know how to make persist into deep time is a very simple clock [2], and even that requires human intervention.

In Anathem [3], Neal Stephenson speculates on what this combo of culture and deep-time technology might look like.
