Not entirely true. Recent versions of bgp support the route refresh option.
This sends a request to the peer to resend it's prefixes when a
router#clear ip bgp soft in
is issued.

The only caveat is that both sides of the bgp conversation have to
support route refresh.  A
router#show ip bgp neighbor
will indicate whether it is supported or not.
