I'm of the "If it ain't broke, don't fix it" persuasion myself.
Of course that does mean inspect often and replace on the slightest suspicion.
I once replaced my forestay pigtail preventively and it pulled out while rigging. It was brand new, done by a trusted specialist, it looked good and even so it failed miserably.
That settled the matter for me, no more replacing stuff that isn't showing signs of weakness.
You do need to inspect swage terminals well though, a casual inspection often will not reveal broken strands held in place by the surrounding intact strands. You need to bend the wire a little to show up hidden defects.
