But I have five words for you Dilandu:
The Proscriptions of Jwo Jeng

Charis (or at least the people in Charis who really matter) already KNOW that the proscriptions are a bunch of junk and that there's no reason why they can't be blown off. Of course we still have to keep the ominous platform in mind, but the proscriptions themselves are meaningless.
Further, in Charis, there's a religious infrastructure that not only accepts innovation but actively encourages it. In the rest of the world - to include Charis' notional allies - there's no such religious infrastructure. To varying degrees, such innovation is still "frowned on" by the Church. In Harchong and Desnair it's probably still a "hanging offense" to work on proscribed things. Perhaps not as draconian in Dohlar, Silkiah, and Siddarmark, but I can't imagine that true innovation would be encouraged there either.
So why did we see so much "innovation" during the war? The Church was confronted by Charis' overwhelming technical superiority and had to do everything in its power to try to compensate. Think of all of Clyntahn's "dispensations"... Dispensations born out of desperation! Now that the burning threat of immediate invasion by those heretical Charisian's is not there, the main driver for the innovation has also gone away.
Just my two cents...
