For scalability.
The OSPF "areas" concept looks quite easy: just use regular VGP routes between "areas".
The only difference is that an OSPF ABR straddles the area boundaries, whereas an AS boundary is between 2 ASBRs in BGP.
The ISIS concept of levels could get interesting if duplicated in BGP SPF.
It joins level 1 domains with level 2 links.

Thanks,
Jakob

to what purpose?
