Do we think the audience is specifically Shin due to the use of 'nimi' as an honorific? It doesn't seem likely that they could have influenced the Shin given the time period. The only other explanation I can think of is that the Shin, or related peoples will later move to populate Komashi. Speaking of timelines, though this seems to be pretty late in the cosmere, where does 1700 years prior fit in? It's such a large timescale that it could predate most of the cosmere, or it could come after everything we've seen so far. All we really know is that 1700 years later, Hoid has met design, but isn't tied up on Roshar and there seems to be a more standardized system of physical interplanetary travel.
