That depends. When the FIB gets too big, routers don't immediately

If you consider blackholing traffic because the relevant next-hops aren't present in the FIB to be looked up as 
"degradation".... I guess?

Come on man, go re-read the post. The two paragraphs you cut literally
explained what happens -instead of- routes dropping out of the FIB or
being black holed.
