I asked a similar question a few years ago:
http://seclists.org/nanog/2007/Aug/653
Most of the answers came back along the lines of "keep your routing
boundaries congruent." Doing so makes documentation and troubleshooting
simpler -- having non-congruent boundaries is more complex and error
prone.
However, if a network you're running calls for non-congruency -- go for
it! Just be cognizant of the trade offs.
