Ah. OK, the changes in boost::throw_exception are in full compliance
with your unsolicited pledge. Its semantics have not been changed,
only extended, and yes (I thought that was obvious) if any library
that uses boost::throw_exception breaks due to the changed semantics,
I *do* treat that as a bug (in boost::throw_exception.)

Though I have no plans to make any changes in the rest of the
Exception library, I can't make the same pledge for anything except
for boost::throw_exception, for now. The difference is that
boost::throw_exception is a simple, mature and proven interface; the
rest of Boost Exception is relatively new, I have only used that code
for about a year prior to the review proposal, and it was first
released in 1.36.

I wasn't expressing an opinion, I was stating a fact. Boost libraries
do change, and occasionally the changes do break existing code, and
occasionally such breaking changes are made on purpose. I apologize
for the perhaps inappropriate tone of that remark.
