A lot of people did it because because there really wasn't a cheap,
dense solution until about 2010. And even then, the traditional strategy
had become so entrenched that running IP all the way in the Access was
such a foreign concept which was most certainly a lot more expensive
than incumbent Layer 2-based Access models.
I feel this has since changed with the current offerings from Cisco,
Juniper and Brocade. The problem now is how to scale the low-speed port
density up, as well as add 10Gbps port density, without increasing the
cost or size of the platforms.
