This seems to be missing or at least conflating the meaning of idempotence.

The draft correctly identifies idempotence as a "property of certain operations", but what the draft seems to describe is locking and caching.

Locking and caching are important to building idempotent operations, but shouldn't be conflated with idempotence which is a conceptual property of the operation.

I like what the draft describes, but it would be better done in the correct context.
