In recent years, separation logic has brought great advances in the world of verification. However, there is a disturbing trend for each new library or concurrency primitive to require a new separation logic. I will argue that we shouldn’t be inventing new separation logics, but should find the right logic to reason about interference, and have a powerful abstraction mechanism to enable the library’s implementation details to be correctly abstracted. Adding new concurrency libraries should simply be a matter of verification, not of new logics or metatheory.
