I would say the issue would be determining whether they are really 
abandoned or not? The issue being overriding the locking mechanism when 
you should not and causing damage to the repo. Any automation would need 
to examine whether the lock is held by a legitimate Borg process or a 
defunct one and honestly I do not know to achieve that.

Because I was using a remote repository, I found that I had to issue the break-lock command on both computers before I could run my backup again.
