You can, but if you have a LARGE IXP (like DECIX or AMSIX etc.), you can cull much more selectively - "we need to work on that particular corner, only ISPs affected to <switch 34> are affected", so you cull BGP to and from there. Other traffic on the fabric is unaffected, and sessions to the affected routers go down nicely - just turning off the ports on "switch 34" will see the peering partners time out...
