Cable stretch has nothing to do with whether the chain will run off the casstte either high or low. The OP should be good to go once the high and low stops are properly set. Cable stretching causes indexing problems.
I take the spoke guards off my bikes when I pull the cassette to do maintenance. I've found that the plastic tends to get quite brittle after a couple of seasons in the sun and tends to break. Al
