Well, I don't see it having been properly debated and calculated. :-)

The whole underlying philosophy of RSPF is at odds with more conventional
routing schemes such as that implemented by gated. My opinion is that it
should be easily configurable as to how /proc/net/route is formatted, and
everyone will be reasonably happy. It makes little difference which is default
as long as it can be changed.

I suppose that, as long as manually adding the route overrides the default
behavior and makes RSPF work, this is best seen as a documentation issue.

You don't want to get me started on gated...
