So you're suggesting that people should reimplement the whole API of 
Boost.Serialization where each function call is wrapped in a try/catch 
with all the expected Boost.Serialization exception types?

Sounds practical. How about Boost.Serialization directly uses a global 
togglable mechanism which can be set to use the feature or not instead?

Typical example code is irrelevant. In real life people build complex 
systems where several things can happen in different threads and you 
need to be able to transfer errors from one thread to the other. You 
also write generic code where you cannot predict in advance what the 
exact type of the exception you're gonna have is going to be.
