The purpose of lock is "to prevent two people changing the same file
concurrently, at least without conscious decision and extraordinary
steps like breaking the lock." That is, it's not just that users
want their commits protected from overwriting (though they want that,
too), but rather that they want to be prevented even from beginning
the work which would eventually collide.

It sounds to me, therefore, as if "[locking] would never get reported
properly" may be restated as "locking would be broken." They would,
I think you're saying, eventually learn that they both modified the
same file (at someone's commit), but the "modify concurrently" would
already be done.
