Its important to note that Ubuntu already did this transition.

Ubuntu 12.04 (releasing tomorrow) ships with MySQL 5.5.22, and 5.1 has
been dropped from future Ubuntu releases. So there is at least some
precedent. The transition went rather smoothly. Most of the fixes done
in Ubuntu packages were pushed back into Debian and have been applied to
the Debian packages. 99% of the problem was packages with build-depends
on libmysqlclient16-dev instead of libmysqlclient-dev.

I would expect a rebuild transition to pickup the new version of
libmysqlclient.  There are a few things which directly recommend or
suggest mysql-*-5.1, but those are, IMO, bugs, as the meta package is
the only one that will always be around.
