Well, CMP leaves pretty much everything to CA policy so it's up to the 
individual CA.  I leave it in the CRL until the cert expires anyway, but 
that's just me (I'm also currently overloading the "undefined" reason code in 
the hope that, since you're not supposed to use it, it's a spare code which 
can be used to mean "never valid", but it really needs its own reason code to 
indicate the true status).
