In a PF rifle it makes sense to have a 3 position safety since you have to cam the bolt over in order to make the extractor snap over the rim so the case can be extracted. In a CRF, all you have to do is move the bolt straight forward and back.
If you need to carry the rifle with a round in the chamber, just hold it vertically with the trigger pulled and chamber a round, then let off the trigger. Then all you have to do is lift the bolt handle to cock it.
