It's a little more nuanced than that. You probably don't want to accept a default from your transit but you may want to pin defaults (or a set of broad routes as I did) to "representative" routes you do accept from your transit. By "pin" I mean tell BGP that 0.0.0.0/0 is reachable by some address inside a representative route you've picked that is NOT the next hop. That way the default goes away if your transit loses the representative route and the default pinned to one of your other transits takes over.
That is a great idea. Get all the utility of default with fewer risks. -- ++ytti
