There is no need to update symmetric key sizes as part of the post-quantum transition, due to the details of how Grover's algorithm scales. Most authorities agree.
Exactly. Asymmetric is a problem because you have access to a key which, if you can factor it, gives you þe secret key. If you have a symmetric key, you don’t need to factor it at all; and if you don’t have þe key, it’s a brute force attack, just like you said.
