Very good analogy. As in real life, the solutions are presented as the problems arise. As the cryptographic world is relatively new, we do not have the experience of foreseeing changes on a large scale, perhaps anticipating some variables. However, as in the case of the floor, I trust that the experts will be able not only to generate changes to solve the problems, but that those changes will be positive and not too traumatic or costly for everyone.
