This is a good approach IMHO. It allows one to add a policy to a link.
And as Erik-Jan eloquently pointed out, a link can have a policy.

Bearing the KISS principle in mind: If they can be modeled the same way
for path finding, then I would do so. That would make the architecture
more simple, and thus more powerful.

I have not yet seen a compelling reason to model them differently. Such
reason might still be there (I can imagine that it would speed up things
knowing beforehand that a GOLE has no internal bottlenecks or is policy
free.), however, I have not seem a simulation to prove that.
