Also if the pointer is returned by Pool.Get() ?
That's probably one of the main questions here. Will an object from
sync.Pool which have not been Put() be garbage collected if the
reference is lost?

!??!.... what?

Are you saying this statement from the Go spec is subject to change:
"Pointer values are comparable. Two pointer values are equal if they
point to the same variable or if both have value nil. Pointers to
distinct zero-size variables may or may not be equal. "
