refcounting gc is very fast and works fine for most of the references. Java not using a combination of both methods is a flaw.

Refcounting is significantly slower under most circumstances. You are literally putting a bunch of atomic increments/decrements into your code (if you can't prove that the given object is only used from a single thread) which are crazy expensive operations on modern CPUs, evicting caches.
Under most circumstances function local variables aren't passed to other threads, or passed at all.
And? That's a small, optional optimization done by e.g. Swift.
Also, I don't know how it's relevant to Go which uses a tracing GC.
