This seems like a good idea.  I was not aware of the work in the other area,
so I believe my primary commment needs to go elsewhere as well:

While it's true that a given node may have a given limit on its readable
depth, this may potentially vary on a per interface basis.  What's the
intent, if any, to accommodate something beyond the least common
denominator?

Editorial nit, your references point to the ospf document twice.
