I'm talking about the following case:

1. libA depends on libB1, but only build-depends on libB-dev
2. libB1 changes to be libB2.
3. libA is rebuilt with libB2 without maintainer noticing (could happen 
  on buildd, etc.), possibly creating a noncompatible interface.

It would be a practical case especially when libB1, libB2 are not 
using versioned symbols.
