I had already understood (and stated in the last sentence... it may have not been clear for you). Yes the message itself is blocked. But you did not reply to the question: why you need to delete that local distinction for Taiwan? For now it is also blocked on the target wikis, but would remain as it is independantly of the state of translations for the regular "Hans" and "Hant" script-based variants, just like there are still local translations for Hong Kong (may be also for Macau or Singapore on some target wikis).
