I also strongly suspect that the final role quest was pieced together rather quickly at the last minute because the development team realised that having a storyline about the Russian inspired race reclaiming their ancestral homeland at the same time as their real world equivalent engaging in a 'special military operation' had the potential to be controversial.

Which sucks, since I don't think real world events should be influencing the direction of the ongoing story but I get it when accounting for the sort of black and white morality large swathes of this game's community cling to.

It might even explain the weird decision to tie Hildibrand to the relic weapon this time around, especially if Corvos was originally planned to be the Bozja and Eureka equivalent. We might still go there at some point though it was name dropped far too heavily and it does seem as though the writers are struggling to figure out where, exactly, to take the Garleans next. That we haven't heard anything in regards to content equivalent to Ishgard's reconstruction efforts is suspicious as well. Other than a passing comment before Endwalker.

All just speculation, though. We'll never know for sure unless they bring it up in an interview.
