Could you explain how it would work again?  I didn't attach a case to the
feature request because I didn't understand all the implications of not
installing a more specific route if a less specific existed.

And this seems to be what started the thread up again:

My understanding is that even with this new feature it wouldn't make any
difference to the routing table size if somebody advertised their /19 as 32
x /24.  Correct?

Thanks,
Lee
