BGP to OSPF Redistribution w/ Sham-Link

I'm curious if this is really necessary? I've done this in my lab and it
seems to work fine. I understand that you MUST redistribute OSPF into BGP on
your PE, so that appropriate VPN labels are advertised to the remote PE.
However, I see no reason to redistribute BGP into OSPF, since the LSAs are
getting advertised through the sham-link, and the CE routers will have a
complete LinkState Database from that.

Is there anything that I'm missing?
