Honestly, I am neutral about this one.  I think it all depends on the
motivation behind the desire to rewrite the log.

If the project that was hosted in Subversion wants to switch (perhaps
gradually) to git, _and_ if the project also wants to adopt a workflow
that does not do the GNU style changelog in the commit log but use a
one-line summary friendly format, then sanitizing the commit log while
importing via git-svn would make sense.  Even though filter-branch after
conversion would be another possibility, that option is only available if
you are converting away from Subversion, never to return.

On the other extreme, if the Subversion side will always be the canonical
one, _or_ if the project does not want to change its commit log format,
then I think it makes perfect sense to limit the commit log munging to the
absolute minimum (but even in such a case, the user can just run git-svn
without activating the log munging option --- so I do not think it is such
a big deal to add or reject an option like this).

That's an independent topic.  If such a filter supports a feature like our
shortlog command has, people whose history is still trapped in Subversion
would benefit from it.
