redistribute bgp considered harmful

[Sean Donelan <sean () donelan com>]

Should the Service Provider version of routing software include the
redistribute bgp command?  Other than CCIE labs, I haven't seen a
real-world use for redistributing the BGP route table into any IGP.

If the command was removed (or included a Are your sure? question) what
would the affect be on ISPs, other than improving reliability by
stopping network engineers from fubaring a backbone?
