We're hoping it won't stay that way forever because it's limiting
to have to rely on offline tools for all traffic engineering :-)

That means that traffic engineering would need to be more dynamic,
and the routers would play a more active role in determining paths
and possibly doing network optimization.  Hence the IGP extensions.
