We have previously explained why this is not a feature we are considering.
The possibility of facing CVs in games forces players to make choices in how they will configure their ships, if you know you will never see a CV, you will never spec your ships for AA and conversely, players who opt to stay in game with CVs will purposely spec for AA. This leads to heavily weighted games in either situation. Furthermore, adding additional criteria's into the Matchmaking system will extend times for games to be formed, and while peak server time would be able to cope, it would cause major impact on the quieter times for the server.
Please consider that this is not an individual ship change, this is a change that is impacting a mechanic within the game as a whole. Which as previously stated when we shelved the concept of altering the GC, would be conducted if it improves the overall balance of the game
"It should be noted that even the ships purchased in or marketed through Premium store are a part of a big game we all play. That means our decision does not isolate any ship from systematic changes applied to a group of ships on common basis or to the whole game. For example, a change to the Radar mechanics affects all ships equipped with Radar, a Smoke mechanics change affects all ships with smoke, etc." - Source
This is a game wide mechanic change that is impacting techtree and premium ships alike.
Please remember, as all proposed changes on the Dev Blog, these are work in progress. This means that depending on testing that will be conducted internally and with the help of our STs/CSTs/CCs determined if it will make it into the game.
