Best practice for BGP session/ full routes for customer

I have quick question on how you provide full BGP table to downstream
Most of large networks have few border routers ("Internet gateways") which
get full table feed and then they have "Access routers" on which customers
are terminated. Now I don't think it makes sense to push full routing table
on the "access routers" and simply their default points to border routers.
In this scenario what is best practice for giving full table to downstream?
1. Having multi-hop BGP session with a loopback on "border router" for
injecting full table in customer router and another BGP session with access
router for receiving routes? (messy!)
2. Injecting full table in just all access routers so that it can be
provided whenever needed?
3. Any other?
Thanks in advance!
