I bought a steel-mesh covered one (not sure how else to describe it) about 20 years ago and it's still going strong. But I always carry a backup; it's about 5 bucks worth of insurance that I wouldn't do without. (The backup release is cloth covered, for no other reason than it was cheap and I only expect to have to use it for a short period of time, if ever.)
As to the question of attaching a cable release to a shutter with stripped threads: I'd personally dedicate a cable release to a shutter like this with some form of tape. 1/2" bellows tape would probably work fine (and would be what I'd use simply because it's what I always carry in my pack).
