Most of the time is configuring a specific customer, and wanting to be sure they are configured right; including the hard case of "no customer AAAAA", that is making sure all configuration for a specific customer is removed. The rest of the time is typically troubleshooting a network level problem where you want the device view we have today, I see interface Gig1/2/3 is dropping packets, "show run" to see who's configure on it sort of operations.

It's not the cleanest, but in junos you can pretty much get this by
defining a configuration group per customer and applying them all. Your RE
