It is slow and clunky because that is what is required to ensure separation.
Separation in IMC in class G should be EVEN MORE clunky because it is being done by pilots who can't issue instructions to other aircraft and don't have an ATC-style big picture of the situation.
If it isn't more clunky than ATC procedural separation, it is because they are not applying the same safety standards.
