Existence does not imply a need for many; it likely implies lack of leadership. Nature abhors a vacuum hence 20,000+ plugins at wordpress.org. Inspect the cache plugins and you'll find common patterns with arbitrarily different implementations.

Not asking for a user feature, asking for more API.  Let plugins innovate on UX not API.

60-80% is better than 0% improvement for those w/o technical skills or budget or ability to understand a bazillion configuration options.

If they were convened I bet they would come up with a base caching API, and APIs are not hard to maintain.

There is a defacto-standard debug bar plugin promoted by the core team. There is no equivalent for caching.

To fix incompatible implementations with otherwise compatible benefits. People innovate on top of APIs but chaos reigns when there are no APIs or they are not sufficiently prescriptive.
