The thing about safety wire is that it wouldn't allow a "loose bolt" to back out completely even if done improperly.
Locktite can just a easily be applied improperly - like to a greasy/oily bolt or a clean bolt in a greasy/oily hole...
When doing Wilwood brakes, and I've done maybe a half dozen sets of 'em, I use locktite AND the safety wire. Personally I like the looks of the safety wire and it's fun to do. But everyone knows I'm weird.
