Nah, usually the ship's namesake city/province government have some connection to the ship administratively, you see them send the crew their local delicacies and gifts. Naming a ship Taiwan before reunification would break that pattern. Guangxi's signature food is 螺蛳粉 so people have been saying on man, that's going to be a biological hazard onboard.
Bruh why you gotta call me a WMD
On topic though it seems the carriers will reserve the coastal provinces/admin regions so thats Liaoning, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong, Hong Kong and Macau (Taiwan can be added after re-unification, Tianjin and Hebei are coastal but seem to be skipped for carriers?). So that's 10 to 12 names available for carriers and 22 to 24 for other capital ships. If there's ever a need for more names though they can always use famous Chinese political/military leaders or something like that.
