A weakness will not come in the form of "it's suddenly broken". It will be a slow decline of worsening performance. Even quantum computing will be moving forward with a gradual rate of growth in Qubits. At some point during this transition, it will break and they will have to transition. It will not be hard to create an new RFC for that task. It will be hard to replace all of the implementations in the field. We are getting better at this with our experiences in TLS but it is still somewhat painful. Crypto agility can be really nice but it can also be messy. Sometimes it's best to be opinionated and sometimes it's easier to just be flexible.
