That feels like a bit of a revisionist take. There certainly wasn't a consensus regarding it being a carrier, let alone a CVN, for "over six months." Even five months ago, members were still arguing for a nuclear icebreaker or a civilian hull. Some were adamant that a carrier was effectively impossible based on the configuration of the keel blocks. And I'm not talking about some fringe or new members but about established and loud voices.
You're emphasizing the value of caution but ignoring the cost of being overcautious. You previously argued that we should wait for confirmation from 'big' sources. We still haven't really gotten that confirmation, yet the reality on the ground makes the conclusion undeniable. If we ignore visible evidence and refuse to apply Occam's razor until one of the major Chinese sources gives us permission to believe it, we lose the ability to track these developments in real time.
