At some point I imagine it's going to be redistributed into the IGP (or re-originated in the IGP), so would think it would be best to just always run the default in the IGP to keep things consistent.

We recently started migrating from "IGP for everything" to "BGP for customers, IGP for 
infrastructure".
We have chosen to go with the default route in IGP, since we consider IGP strictly 
internal (no redistribution allowed anywhere) and something to be trusted more than BGP.
