No, I'm not saying that every change in the library implementation
should be reviewed. But in case of Karma we have a major change in the
Spirit feature set, and the new functionality is not related to parsing
(the domain, in which Spirit was once proposed and reviewed). Such
changes, IMO, should be reviewed, because they are equivalent to a new

That is a good point if taken from the Boost point of view. As for
users, such duplication really complicates their lives. A user has to
learn both libraries, chose what he likes more and then get caught by
surprise because his fellow co-worker have chosen the other one.
