Since you can't take a full feed from either upstream, partial routes
will mean taking your upstream's own routes + their directly-connected
customers + default.
You may make it more flexible by asking for their peering routes also,
but if these are large global transit providers, that could be the full
BGP table anyway (or 90% of it).
