Because it's totally different protocols.  One is "take this packet, slap
a label on it, send it out according to LFIB" - which current switch hardware
can easily do.  The other one is "... and add a layer of IP encapsulation"
which isn't that hard on the sending side, but more complicated to get 
right on the receiving side - "complicated" = "transistors on the silicon"
= "engineering trade-offs".

Switch = things done in silicon, fast and dumb

(Yes, I understand that a 2015 switch cannot be compared to a 2000 era
switch, but the general principle holds - "what is not in the silicion
can not be done with reasonable throughput, if at all")
