Poland and Hungary are already promising to not abide by the slightly positive things the asylum reform brought: Distributing refugees fairly across Europe from the nations they arrive in.
Interesting how these two far right countries can promise to disobey by the law, but only the humane aspects, and will likely face no repercussion for that. This will be shocking for you to hear, but I think no other nation will break this reform in order to, for example, prevent refugees from being deported to random “safe” (non-European) nations.
Given the precedent of European nations, especially Germany, simply not doing whatever the EU asks of them whenever it doesn't suit them, I think you should understand what is possible if politicians and our capitalist economy cared.
