Yes it is, because in reality boost exception solves problems for the
users of any library that uses it. When using boost exception I can
safely let exceptions escape threads and have them rethrown in the
starting thread, for instance.

It has a real and important reason, because it unifies boost exception
handling, nearly for free. The few boost libraries which do not use it,
serialization most notably, cause trouble because they need extra care
to make exception handling well behaved.

No, it gave your users more functionality in an area of which you were
not even aware.

It is a shoulder (not quite a giants, but still) to stand on, which
gives you a higher reach!
