Minimizing ossification risk is everyone’s responsibility
Building protocols in a way that anticipates future change in order to prevent ossification is critical. Because it’s impossible to upgrade everyone on the internet at the same time; it needs to be possible to introduce changes gradually, without harming communication where only one party understands the change — and this is everyone’s responsibility.
