Rxjava: Why is there no share or publish/refcount for single?
RX Java version 2.0.4 - Single doesn't have share/publish/refcount and therefore we can't have hot observables. Is there any reason for the same.

It has a cache operator and a SingleSubject to help with many cases when the single item should be cached. You can always convert back to Observable and have access to the publish and refCount operators.

I come back to the issue. Could we have more context about the "why" there is no "share" operator for single ? Even if we can maybe solve some requirement in another way. Is it by design decision ?

We limit the API surface of the library and the need for share in other types is rare.
