For main bases, i agree. There needs to be deterrence. A map like Gazala for instance. german base already has 2 88s and a flak gun but allied base needs more.
For center of maps, I would suggest this done with caution and only when AA played such a pivotal role.
Dont forget the stone paper scissors of it all.
Infantry cant just march to the enemy base and disable its AA. Planes kill static guns, which kill tanks, which kill infantry which kill AA, which kill planes.
You need to account for the other elements in that relationship.
And 2 or 3 airplanes coordinated should still be able to take out enemy AA, even at the main base, especially since arty wont get that far
