There's corporate data centers and there's colo data centers. The two are
sufficiently different that the requirements are divergent.  For starters,
in a colo, the guy on blade 3 port 5 is quite possibly a competitor of
the guy who's got blade 2 port 17.  In the corporate data center, we
maintain the polite fiction that those two are working together for
a common goal.  This has implications for security features, billing,
bandwidth engineering, and almost every other feature on a router.
