I'd argue that bolts connections on a bicycle that require thread locker to stay tight aren't properly designed (or assembled).
In my experience:
I always use anti-seize on the threads, removing any factory-supplied thread locker.
Yet to have a brake bolt come loose.
Of course, it is possible. And yes, some people don't notice those things, until they completely fall off (sometimes not even then). Suppose that those plastic clips are a good idea for such cases (and the main reason I don't throw them away).
