Request: Add operator to cache only onSuccess value from Single
See original GitHub issueBasically like Single#cache but that would re-subscribe to source if it previously terminated with onError.
Use case: caching network responses in memory. Single#cache is not suitable for this purpose because we generally don’t want to cache network errors but instead retry the request on subsequent subscriptions.
This is what we currently use https://gist.github.com/technoir42/93cf3647aa869dde498b0afe663c83ea (based upon Single#cache).

Such behavior seems to be peculiar to your use case and you did a good job implementing a solution for it locally. I’m not convinced the operator should be added to RxJava though.
